I see more than half in the poll picked her because she's "electable" rather than actually liking her.
Yeah.. that says a lot about her and also explains why she lost to Obama in 2008. But to be fair to the Dems, many Republicans also probably only support Bush because he has the best chance of beating her and not because they like him... or at least I hope so lol.
At the end of the day, what matters most is not who's likable but who they want to vote for - look at California's 2002 governors race for an extreme example.
