Catholics who vote primarily based on abortion
But Wagner and Barletta are much more pro life than both Casey and Wolf by miles.
In addition to Mizzouian's point about Democratic-leaning Catholics, they could also be making the same calculus that I make regarding JBE if they're single-issue voters. Sure, his opponent is probably an even stronger opponent of abortion, but having an anti-abortion Democrat is significantly more valuable to the national movement than just another anti-abortion Republican. It shows that abortion is opposed in both parties, which increases the credibility of the argument against it, and it also preserves some hope that the issue can be raised above partisanship once again.
