Sitting governors so rarely run for president anymore. Richardson was the only one who did it in either 2004 or 2008. Daniels might do it in 2012, but he'd be in the last year of his second term. Though I guess it's possible you could get someone like Romney....serve one term as governor, then opt out of a second term so you can focus on appealing to the GOP base and setting up a run for prez. Not sure who that would be though. Rick Snyder? Bill Brady?
To be fair, Clinton and Bush Jr. ran for President as incumbent Governors. 1992 and 2000 was kinda recent.
