Certainly enough of them did; as a Catholic it is shameful to me that Dems do best mostly in areas with the highest concentrations of Catholics.
For decades this was true, and it may still be true: Every state with 80% or more Catholics had two pro-abortion Senators. Every state with single-digit Catholics had two pro-life Senators.
The bishops have twisted themselves into pretzels to keep Catholics voting Democrat. Cardinal Bernardin’s “Seamless Garment” was worth $20 Billion to the abortionists and the Democrats. The USCCB is the most effective PAC the Democrats have. It propagandizes for them, and helps logistically in bringing in endless hordes of invaders.
