Catholic Support Slipping?

Amy Sullivan of Time Magazine reports that Obama is already losing support from Catholic voters.

I said during the campaign that Catholics were fooling themselves if they believed Obama was the "real" pro-life candidate. And now they are realizing the truth.

It's a bit of buyers' remorse now. The question, of course, is the impact. Will Obama lose a huge voting bloc when it comes time for reelection (assuming the country survives that long)? Or will this all be forgotten by then? My guess is that if he continues along these lines, more Catholics will feel the same way as those at Notre Dame, who protested the President's visit.
