My mother was wondering the other day how Obama ever got elected when so many Catholics went down for the March for Life.
Answer: those very same people pulled the Democrat lever because their union (or some other form of self-interest) told them to do so.
I am a regular participant in the March for Life. I don't agree with you. Eevidence obtained by talking with folks there suggests that, quite simply, you are wrong. These are NOT demonicRat voters.
The Catholics at the March (the adults, anyway) are a subset of (for lack of a better term) the "True Believers"; those who believe and practice the Church teachings. "Practice" includes voting.
During a very good year, the March will draw a few hundred thousand folks, mostly Catholics. That's a small subset of the Catholic Population of these United States. It's even a small subset of the about 50% of Catholic voters who regularly vote for Republicans.
Fecal logic. Catholics who march against Roe v. Wade in the rain don't vote for pro-infanticide candidates.
