i've followed him very closely, and I like him. I'd probably vote for him over the other 2.
There aren't any perfect candidates. I want Obama to be a new JFK and restore America as the shining star in the world. But I have to admit, I've seen him slip up and say some non-presidential things in the debates. Hilary and Obama ticket is something I'd actually PREFER... With Obama as prez, shaking hands and being humble and dignified face of USA, all while Hilary makes changes necessary to recover the economy. Bill did it, and I think hilary clinton can too.
Bill was a brilliant speaker, not some policy genius. His legacy benefited from a bull market (that stumbled near the conclusion of his presidency). If you look closely at his policies, they were not particularly innovative. I don't blame him.... not every president serves in a time that fosters greatness (FDR, JFK, LBJ to an extent...)
Hillary has nothing on Bill. She's not near as smart, or as charismatic. But she's equally willing to lie. Having her in power would only be slightly less catastrophic than having McCain.
Barack has not carried all before him in debates, but he does not need her for anything.
There is no experience that prepares people to be president. Herbert Hoover was twice (wildly successful) secretary of the Treasury before he became president.... then the Great Depression happened.
