During the 2012 presidential primaries, 51 individuals sought the nomination of the Democratic Party. Incumbent President Barack Obama won the nomination unanimously at the 2012 Democratic National Convention and was re-elected as president in the general election by defeating Republican nominee Mitt Romney.As expected for the incumbent president, Obama won every primary election, but faced more difficulty than projected. Fifteen additional candidates appeared on primary ballots, and of these, four appeared on more than one ballot. Four qualified for convention delegates including: attorney John Wolfe, Jr., prison inmate Keith Russell Judd, perennial candidate Jim Rogers, and anti-abortion activist Randall Terry. Each of these had their delegates stripped prior to the convention due to technicalities.
The following candidates earned at least 5% of the popular vote in any contest:
