I would still appreciate it if anyone has anything concrete to refute this stuff, though. I'd like to know if it was made up of whole cloth--or did Fred at one time support some of this, and has since changed his mind about it and moved on
I can't speak to all of the accusations made against Thompson, but as for the claim that he supports abortion it is flat wrong. Fred's Senate voting record is 100% pro-life, and he got a 100% rating from National Right to Life, the largest pro-life org in the US. If the source of your article would lie about that part of Fred's record I wouldn't give him or her any credibility on the other points either.
