This Catholic will continue to only vote for PRO-LIFE REPUBLICANS.
I have never voted for a democrat in my life and I never shall.
You're lucky to have "pro-life Republicans" to vote for. If you're old enough to have voted for Ford, you voted for a pro-abortion Republican. In fact, until the turmoil around Roe v. Wade (and presumably the money ripe for the plucking from NARAL, etc.), the strongest voices against abortion were Democrats -- Republicans on the whole didn't see what the fuss was about. I'm trying to think of any strong voices against abortion today in either party (there are very few); McCain's voting record was generally anti-abortion, but I don't recall his mentioning it in the campaign, and I don't recall that he was really inclined to knock himself out on the issue. His "gang of 14" harmed the cause immeasurably.
The MA state Republican party has no anti-abortion plank in its platform; there was some discussion about putting a pro-abortion plank in a few years ago. I think it was while Cellucci was governor -- Cellucci, the Republican who spoke enthusiastically at a "Reproductive Freedom" rally. From what I see on FR, a number of the state Republican committees are no better.
I read a few years ago that a lot of the really big Republican donors either don't care about or are hostile to the social issues, including abortion; the article (sorry I don't remember who wrote it) said that this explains why Republicans will say enough about the social issues to get elected by conservatives, but in so many cases just don't put up much of a fight.
