My feeling is, and this is only my opinion, that after millions and millions of abortions, there are a lot of women out there that KNOW what they did was wrong, feel betrayed by the feminist party and will try to rectify what they did, in part, by voting pro-life. And I'm sure a big chunk of those women are catholic.
Again, JMHO
I think you are probably right, but something I suspect that is first needed is the prospect of absolution -- recognition that what they did was wrong but that our Lord is a Lord of mercy, who would rather that we all turn from our wickedness and live.
