Main article: United States Senate election in New Hampshire, 2010

Three-term incumbent U.S. Senator Judd Gregg (R-N.H.) was reelected in 2004 with 66 percent of the vote. Gregg had originally announced his intention to run for a fourth term, but was nominated to the position of United States Secretary of Commerce by President Barack Obama in early February 2009. However, Gregg withdrew his nomination on February 12, 2009, citing "irresolvable conflicts" over policy related to the Commerce Department. Since then, Gregg stated that he would not seek reelection to the U.S. Senate.

Democratic senators defeated in primary election (1 seat)

Arlen Specter of Pennsylvania

Main article: United States Senate election in Pennsylvania, 2010

Five-term incumbent U.S. Senator Arlen Specter was reelected as a Republican by a 53% to 42% margin in 2004. On April 28, 2009, Specter announced that he would leave the Republican Party and seek a sixth term in 2010 as a Democrat.

Based on polling, the 2004 primary results and a smaller, more conservative Pennsylvania Republican primary electorate, Specter judged that he would lose the Republican primary, and since Pennsylvania law would bar him from running as an Independent under such circumstances, he decided to switch parties. As a long-standing moderate, Specter had had tensions with the conservative base of the GOP dating back to 1987 when he played a key role in derailing President Ronald Reagan's nomination of Robert Bork to the U.S. Supreme Court. Recently, Specter had further antagonized the GOP base in Pennsylvania by voting in favor of the American Recovery and Reinvestment Act of 2009 otherwise known as the Economic Stimulus Bill. In return for joining the Democratic Party, President Barack Obama, Vice President Joe Biden, Governor Ed Rendell and Senate Majority Leader Harry Reid all discouraged candidates from challenging Specter in the Democratic primary.

Retired U.S. Navy Rear Admiral and current U.S. Representative Joe Sestak of Pennsylvania's 7th congressional district announced on August 4, 2009, that he would challenge Specter for the Democratic nomination despite the support for Specter amongst the Democratic establishment. Specter was thought to be favored until polls two weeks before the Democratic primary began showing a dead heat between him and Sestak. On May 18, 2010, Sestak defeated Specter in the Democratic primary by a 54% to 46% margin.

On the Republican side, former U.S. Representative and former President of the Club for Growth Pat Toomey, who came within 1.7 percent of defeating Specter in the 2004 GOP primary, announced that he would run for the Republican nomination. Former Governor and 2008 Republican presidential candidate Mitt Romney has endorsed Toomey. Other Republican candidates include businessman Larry Murphy, who challenged Specter in the 1998 GOP Senate primary, 1994 and 1998 Constitution Party gubernatorial candidate Peg Luksik, and retired Federal Air Marshal Robert Townsend.

In 2008, Barack Obama received 54.47 percent of the vote in Pennsylvania while John McCain received 44.15 percent, a 10.32-percent margin of victory for the Democrat.

Republican senators defeated in primary election (1 seat)

Bob Bennett of Utah

Main article: United States Senate election in Utah, 2010

Three-term U.S. Senator Bob Bennett (R-Utah) was reelected with 69 percent of the vote in 2004. Bennett intended to run for reelection. In May 2009, Bennett released an early advertisement, in which Mitt Romney expressed his support for Bennett, to discourage a primary challenge.

At the May 8 Republican nominating convention, Bennett was defeated, finishing third in the balloting and resulting in him not being eligible to run in the Republican primary that was held June 22, 2010 and featured the top two finshers, Tim Bridgewater and Mike Lee. Bennett's defeat in the convention somewhat raised Democrats' hopes of winning the seat in this heavily Republican state. In a mild surprise, Lee narrowly won the Republican primary and will face Utah Alcoholic Beverage Control Commission Chairman Sam Granato in the general election.

In 2008, John McCain received 62.24 percent of the vote in Utah while Barack Obama received 34.22 percent, a 28.02-percent margin of victory for the Republican.

Lincoln received a tough primary challenge from Lieutenant Governor Bill Halter who entered the race on March 1, 2010 and raised more than $1 million in his first 48 hours. In the primary, Lincoln finished with less than a majority and faced a runoff with Halter. On June 8, Lincoln won the runoff by a 52% to 48% margin.

Three-term incumbent U.S. Senator Barbara Boxer (D-Calif.) was reelected with 58 percent of the vote in 2004, but had difficult races in 1992 and 1998. In February 2007, she announced that she would seek a fourth term in 2010. Boxer won the Democratic Senate primary on June 8 with only 80 percent of the vote which could cost her the general election in November. "The surprise runner-up: Hollywood producer Brian Quintana, who snatched almost 15% of the vote." Blogger Mickey Kaus received the remaining 5%.

Boxer is widely considered by political analysts to be a relatively vulnerable incumbent in the 2010 election cycle. Boxer is facing a tough challenge from her major opponent, Republican businesswoman Carly Fiorina, according to several recent polls. Fiorina, former Hewlett-Packard CEO, defeated State Assemblyman Chuck DeVore, as well as former Congressman Tom Campbell, for the Republican Party nomination.

Donald J. "Don" Grundmann has filed paperwork for the American Independent Party nomination.

Jerry L. Carroll has filed as an Independent.

In 2008, Barack Obama received 60.94 percent of the vote in California while John McCain received 36.91 percent, a 24.03-percent margin of victory for the Democrat.

Michael Bennet of Colorado

Main article: United States Senate election in Colorado, 2010

Following the resignation of one-term U.S. Senator Ken Salazar (D-Colo.) to become President Barack Obama's Secretary of the Interior, Governor Bill Ritter selected Michael Bennet, the former Superintendent of Denver Public Schools, to fill Salazar's seat for the remainder of his term. Bennet won his party's nomination in the August 10, 2010 primary election, fighting off a stiff challenge by former Speaker of the Colorado House of Representatives Andrew Romanoff. Romanoff received the endorsement of former President Bill Clinton while Bennet has been endorsed by President Obama.

On the Republican side, former Lieutenant Governor Jane Norton, Weld County District Attorney Ken Buck, former State Senator Tom Wiens, and businessman Cleve Tidwell have announced their candidacies.

Four-term incumbent U.S. Senator and Senate Majority Leader Harry Reid was reelected with 61 percent of the vote in 2004. He will seek a fifth term in 2010.

Harry Reid is widely considered one of the most vulnerable incumbents in the 2010 election cycle. He is facing a very tough challenge from his major opponent, former State Assemblywoman Sharron Angle in the general election.

Main article: United States Senate election in Iowa, 2010

Five-term incumbent U.S. Senator Chuck Grassley was reelected with 70 percent of the vote in 2004. He has announced that he will run for reelection. Conservative Republicans suggest Grassley may face a primary challenge due to his lack of support for their issues. Potential Republican challengers to Grassley include conservative activist Bill Salier, who said, "Grassley was the dominant force and had an enormous amount of loyalty. That has so eroded out from underneath him" during an interview on WHO-AM radio.

Former U.S. Attorney Roxanne Conlin former state representatives Bob Krause and Tom Fiegen are running for the Democratic nomination. Krause has said that Grassley's more than half-century in public office is too long. "As a good farmer, Senator Grassley must recognize that 51 years, or 58 years at the end of his term, is a long time to go without rotating crops," Krause told about 50 supporters in Des Moines. Krause cited Grassley's support in 1999 for legislation that allowed banks and insurance companies to begin offering other investment products. "Please remember that farmer Grassley was one that opened the barn door and let the cow out at AIG," Krause said. On June 8, 2010, Conlin won the Democratic nomination.

In 2008, Barack Obama received 53.93% of the vote while John McCain received 44.39%, a 9.54-percent margin of victory for the Democrat.

David Vitter of Louisiana

Main article: United States Senate election in Louisiana, 2010

One-term incumbent U.S. Senator David Vitter was elected with 51 percent of the vote in 2004. This was actually an impressive victory considering Louisiana's election process in 2004 was an all-party "open primary" where candidates of all parties and no-party ran together in the same election. In receiving 51% of the vote Vitter won the election outright without the need for a runoff election. Former U.S. Representative Chris John, a Democrat, finished second to Vitter with only 29 percent of the vote. Five other candidates completed the field receiving 20 percent combined. Vitter has announced that he will seek reelection, though his reelection bid may become complicated by a prostitution scandal that was revealed in 2007.

Secretary of State Jay Dardenne (R-La.) was a potential challenger to Vitter in the Republican primary, as was pornographic actress Stormy Daniels. Retired Lieutenant General Russel L. Honoré is strongly considering running in 2010 as a Republican, with one source saying that the ex-U.S. Army commander was "more than 50 percent sure that he will run."

U.S. Representative Charles Melancon of Louisiana's 3rd congressional district, who is the only Democrat in Louisiana's seven-seat delegation in the U.S. House of Representatives, announced on August 27, 2009 that he would seek the Democratic nomination for the seat.

Anthony "Tony G" Gentile of Mandeville announced on June 16, 2009 that he would seek the Libertarian nomination for the seat. Gentile was a gubernatorial candidate in 2007 and a congressional candidate for Louisiana's 1st congressional district in 2008.

In 2008, John McCain received 58.56% of the vote in Louisiana while Barack Obama received 39.93%, a 18.63-percent margin of victory for the Republican.

Richard Burr of North Carolina

Main article: United States Senate election in North Carolina, 2010

One-term incumbent U.S. Senator Richard Burr was elected with 52 percent of the vote in 2004. Burr is considered a potentially vulnerable incumbent due to his poor approval ratings and low profile statewide. Burr will be challenged in the May Republican primary by Asheboro businessman, community leader, and sitting City Council Member Eddie Burks.

Army veteran and frequent candidate John Hendrix, attorney Kenneth Lewis, former State Senator Cal Cunningham and Secretary of State Elaine Marshall are running for the Democratic nomination.

On June 22, 2010, Elaine Marshall and Cal Cunningham participated in a runoff primary election for the Democratic nomination as no candidate reached the necessary 40-percent vote needed to win outright. Marshall received approximately 60 percent of the vote to secure the Democratic nomination.

Michael Beitler is running as a Libertarian.

In 2008, Barack Obama narrowly carried North Carolina with 49.70% of the vote while John McCain received 49.38%, a 0.32-percent margin for the Democrat.

Tom Coburn of Oklahoma

Main article: United States Senate election in South Carolina, 2010

Incumbent U.S. Senator Jim DeMint was elected with 54 percent of the vote in 2004. DeMint has raised $2.2 million for his intended reelection bid. He is considered safe, but Democrats blame him for holding up the confirmation of Erroll Southers to the Transportation Security Administration. DeMint also said in July 2009 that the defeat of health care reform would be Obama's Waterloo.

In a major surprise, unemployed military veteran Alvin Green won the Democratic primary to oppose DeMint.

In 2008, John McCain received 53.87 percent of the vote in South Carolina while Barack Obama received 44.90 percent, an 8.97-percent margin of victory for the Republican.

John Thune of South Dakota

Main article: United States Senate election in South Dakota, 2010
