Obama is still no Powell

I wrote previously that Barack Obama is no Colin Powell, and I still think that's true in regard to stature, credentials or even popularity, but John Fund writes (here) that Obama is like Powell in another way: he could very well opt out of a future presidential run. I, for one, think Obama's pure ambition far outstrips Powell's, and Obama is less likely to make the same choice as Powell.

Like me, Fund thinks that much of Obama's appeal stems from Dem concerns about Hillary's electoral shortcomings.
