Based on polling, the 2004 primary results and a smaller, more conservative Pennsylvania Republican 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 has 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, Pennsylvania Governor Ed Rendell and Senate Majority Leader Harry Reid all discouraged candidates from challenging Specter in the Democratic primary.
For the Democrats, retired U.S. Navy Rear Admiral and current U.S. Representative Joe Sestak (PA-7) announced on August 4, 2009, that he would challenge Specter for the nomination despite the support for Specter amongst the Democratic leadership.

Chuck Grassley of Iowa
United States Senate election in Iowa, 2010
Five-term Republican incumbent Chuck Grassley was reelected with 70% of the vote in 2004. Grassley will run for reelection.[207] Conservative Republicans suggest Grassley may face a primary challenge due to his lack of support for their issues.[208] Among those is 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.
Lawyer Roxanne Conlin, former state legislators 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, Sen. 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.

David Vitter of Louisiana
United States Senate election in Louisiana, 2010

In receiving 51% of the vote Vitter won the election outright without the need for a run-off election. Congressman Chris John, a Democrat, finished second to Vitter with only 29% of the vote. Five other candidates completed the field receiving 20% 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.
Republican Secretary of State Jay Dardenne 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-United States Army commander was "more than 50% sure that he will run."
Democratic United States Congressman Charles Melancon (LA-03) announced on August 27, 2009 that he would seek the Democratic nomination for the seat.
Libertarian from Mandeville Anthony "Tony G" Gentile announced on June 16, 2009 that he would seek the Libertarian nomination for the seat. Gentile was a candidate for Governor in 2007 and U.S. House District 1 in 2008.

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