Yup, I think that's true. The point I was trying to make about Rudy and Catholics is that a large majority of pro life Catholics were Reagan democrats who have made the switch, they now vote in Republican primaries. And they vote their because of the social issues. Your point is a good one that puts emphasis on why I don't think Rudy can beat McCain.
In 2004, liberals sneered at some Catholic clergy who made a big fuss over sKerry's pro-abortion record. Come 2008, the same liberals will praise the clergy should they complain about Rudy's social issues stance.
