There are a lot of self-deluded Catholics, then.
More likely a lot of people who think they are Catholic but aren't; having earned themselves a latae sententiae excommunication by their involvement in the pro-abortion cause.
There sure are, but the election in '04 gave me some hope - my best friend, a far better Catholic than I will ever be, and a lifelong Democrat, could not bring herself to vote for Kerry. She had managed to vote for all the Protestant pro-abort candidates, but said that the Catholic Kerry knew better. I was REALLY hoping for another pro-abort Catholic Democrat this time. Maybe Obama will pick Bob Casey (whose Dad is undoubtedly spinning in his grave) for his running mate.
You can add Baptists, Methodists, Presbyterians, and every other sectlet claiming to be Christian to that list as well. The vast majority of folks backing bambi who call themselves Christian are NOT Catholic, after all.
