text: 2012 Democratic Party presidential candidates
Candidates -- Challengers
The following candidates appeared on only one primary ballot .
During the 2012 United States presidential election, 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 pro-life activist Randall Terry. Each of these had their delegates stripped prior to the convention due to technicalities. Thirty-six additional candidates filed with the Federal Election Commission (FEC) to run for president, but either withdrew from the race before the primaries or did not appear on any primary ballots.
