2008 United States Senate election in Delaware

Biden had first been elected to the Senate in 1972. He won his sixth term in 2002, defeating Republican candidate Raymond Clatworthy. Delaware is considered a "blue state", having last voted for a Republican presidential candidate in 1988. By 2008, there were only two Republicans who held statewide office. == Candidates and primaries ==

• Joe Biden (Democrat), incumbent senator since 1973 In January 2008, following a poor performance in the Iowa Caucus, Biden ended his 2008 presidential bid to instead focus on running for a seventh term in the United States Senate. He was unopposed within his party. On August 23, the Democratic Party's presidential nominee, Illinois Senator Barack Obama, announced that he had selected Biden to serve as his running mate in the presidential election. Under Delaware law, Biden could run simultaneously for both his Senate seat and the vice presidency, which he decided to do. O'Donnell had previously run in for Delaware's Class One Senate seat in 2006. After losing the Republican primary to Jan C. Ting, she ran in the general election as a write-in candidate. She lost, having received less than five percent of the vote. The primary election was held on September 9, 2008. Both candidates ran unopposed. == Predictions ==

Pundits believed Biden would easily win re-election, with all major polls placing him over 30 points ahead of O'Donnell. The first poll, conducted in mid-September by Fairleigh Dickinson University, gave Biden the best projection with a +43 margin; his weakest projection came from SurveyUSA, with a +32 margin. The final poll of the election was conducted in late October by SurveyUSA, projecting Biden to win by 34 percent. == General election ==

Biden largely ignored the election in favor of Obama's presidential run. Biden put up very few campaign advertisements; Kristin Murray briefly served as the campaign manager for O'Donnell, later saying she left the campaign willingly because of O'Donnell's financial situation; O'Donnell said she was fired.

A few weeks after the election, The News Journal published an opinion piece by Greg Gober on Delaware's election laws. Gober found the result unfair and undemocratic as Biden's replacement was not voted on. He also criticized Biden himself for his dual campaigns. Biden took the oath of office in the Senate chamber with his fellow senators-elect on January 3, 2009, but resigned his seat on January 15, 2009, and assumed the vice presidency five days later. Outgoing Delaware Governor Ruth Ann Minner appointed Ted Kaufman, a Democrat and longtime Biden advisor, to fill the vacant seat pending a 2010 special election, where Kaufman stated he had no plans to run. O'Donnell once again ran unsuccessfully for the seat, losing to Democrat Chris Coons. In 2015, she was sued by the Federal Election Commission (FEC) for misuse of campaign funds and was found guilty a year later. == See also ==
