Speaking of the A-word, it's likely to remain a much less partisan issue ITTL. The Religious Right per se, is a dead letter electorally and socially speaking (largely because there is no way in hell Catholics would throw in behind the idiots in the AIP), which means that many conservative Catholics who OTL became Republicans are still ITTL still good Democrats. You have to remember it was not until the 1980s that Catholic Democratic politicians were convinced standing with the bishops was a lost cause. Heck, even Ted Kennedy was pro-life until around the time of the Bork crisis. So ITTL a pro-lifer will be as likely to be a Democrat as a Republican. Same would be true of the pro-choice side as well. The main predictor of sentiments on the issue would be primarily sectarian, not partisan - many Catholics of course being on the pro-life side, while many Protestants (including IIRC the Southern Baptists) being less so.
