Whoever it is will certainly be hideous, and quite possibly not based on resume, but on the ability to enrage conservatives (like BHO) because that has become the primary motivator for liberals.
So on that list, IMHO, will be Michelle Obama, and Chelsea Clinton. I’m serious.
My view is that the Dems found with the election of Obama that qualifications, experience and even personal attractiveness were not really necessary after all: the only thing that matters is being a celebrity. Obama was the Kardashian of the political world, a nobody whom they successfully sold simply through massive publicity. Voters didn’t even ask what he had ever done, what his ideas were, or anything about his background because it wasn’t necessary. He was a celebrity and, on top of that, a black celebrity.
So I think it not at all unlikely that Michelle Obama will be the Dem candidate. Or, if they can get the celebrity machine going fast enough, it could be Chelsea Clinton.
