Because the politicians I vote for have proven pro-life records, Rooty Toots openly supports abortion (and my suspicion is that a majority of the Rooty Rooters support abortion as well).
I doubt very much Rudy supports "abortions" (the act itself). Though he may support the notion that it is not the federal govt's role (or courts) to regulate it. Perhaps giving it back to the States to decide individually.
The WH is a job title that requires a larger mind frame then simply tying oneself to a one-issue voting base. Especially understanding that the pro-life side is winning. Facts, education and technology are all pushing the tide for the pro-life'ers.
Rudy agrees with conservative judges on the whole. That he may differ on the issue of abortion is immaterial on the whole.
