Obama is more the post-1960s radical whose approach is more Fabian socialism. For that reason, he could be the more dangerous of the two in terms of presenting a "pretty picture" and seeming more charming and acceptable and approachable than the more dogmatic and ruthless Hillary. But then again, Hillary may destroy him before he gets too far.
Well, if we take the recent French elections to heart, an unattractive candidate, even if she is female, trumps all other criteria. Hopefully, Hillary will be as unattractive to the general electorate as she is to Freepers.
I agree that Barack is dangerous. His problem is that, with his core beliefs taken away, he is an empty suit.
