As far as bagage is concerned. McCain has baggage, Newt has baggage and Rudy has baggage... and certainly Hillary has baggage, so I'm not certain any of the candidates are going to want to get into their marriages... does Hillary want pictures of Bill and his Canadian Mistress all over the news?
I'm no fan of Mitt Romney, but at least he does not have baggage, so far as I know. He appears to be a clean cut, clean living Mormon, a plus in the view of this evangelical Christian, theological differences aside. However, his record as governor of Massachusetts was a liberal one, especially on issues as homosexual rights and abortion, and his father, George Romney, was the epitome of a Rockefeller Republican in the 1960s. I don't believe his conversion to conservatism is sincere, as it coincided with his ambition for national office.
Does Hillary?
She could watch Bill having sex with another woman and, it would not change one thing of her running for president.
Of course I can't really blame Bill for staying as far away from her as he possibly can.
Besides, with those fat legs of hers she could possible kill the man.
