Why did Obama resign? That, and the defeat of a sitting vice president in the primaries, implies some kind of catastrophe. An even matchup would be President Clinton running for reelection, but I doubt Trump would or could lead a Rust Belt revolt in 2012 against a Democrat who won on a populist campaign. Here, he would be perceived as taking on a corrupt and power-hungry insider from a failed Obama administration. And even if Obama was retiring just to retire, that wouldn't be good optics. A campaign to continue the legacy of a young guy who probably hasn't gotten much done yet and chose to give up looks bad.
