Who is the least electable among the top candidates from both parties?
Isn't that another way to arrive at an answer?
Or,
Who holds out the best chance for a big margin win against any challenger?
As a lifelong Democrat I know two things:
The least electable Democratic candidate is Senator Clinton, and
Barack Obama has the biggest general margin upside (since Senator Clinton can't overcome the almost 50% of Americans who already will affirmatively vote against her.)
