Rudy is "PRO" a lot more than just abortion. His social politics are repulsive to many conservatives.
Pete Wilson was probably the best candidate the Republican Party had to offer in 1996, and could have-theoretically-defeated Bill Clinton if given the opportunity.
Instead what transpired was a gross distortion of his stances on that issue-as well as immigration reform-which was trumpeted by the liberal media, and which resulted in his being denied potentially lucrative fund raising sources, and being forced to prematurely withdraw from the race.
I'm not saying that Rudy is the best choice-or even a good one-for the 2008 ticket, only that we shouldn't preemptively blackball one of the more talented, appealing members of the GOP because he might-emphasis on that word-have national ambitions.
