As we all know, NAFTA was supported by Republicans and signed in by Bill -- who is still a Democrat's Darling --popular with his party. So Hillary's problem has little to do with differences between Clintons and Obama on policy issues (they're both liberals) - and more to do with her being a woman and vulnerable to lose in the fall because of her bad history and her bad press, I suspect.
I haven't thought of her in such negative terms as a person --as the media and comedians have --blaming Bill's infidelities on her alleged coldness and lesbian tendencies, etc. (which tendencies are fictional, I believe. I think she really IS some Tammy Wynette standing by her man! But baking cookies would have been good for her image! ) I just think she is too liberal on the social issues and wants socialism --wants gov't to have the power. She said that. "We are going to take away the power of the...." health care industry, I believe it was. The WE was the federal government --taking away the power of the people, in my opinion.
The Republicans are just waiting to bring out the fact that Obama has these real estate and investment items in his history that show him to be another shady, self-serving, free-enterprising dirty capitalist with questionable ethics like the Clintons--or at least financial ties to people of dubious character.
When all sides get through with negative campaigning, there will be no heroes left. If Obama and McCain are smart enough, they will stay above the fray --even if their parties and supporters don't --because they both have skeletons hanging out of their closets.
