While I don't agree with ExtremeConservative's views, by saying that a Republican is better than a pro-life Dem, he's confirming that he's not a single-issue voter, so I'll give him that much.
Here's a question for ExtremeConservative: in the unlikely event there is a race between a pro-choice R and a pro-life D, who would you pick?
Before you ask, I would pick the D, because abortion isn't one of the most important issues to me.
I guess I could have missed something here, but are you referencing this post?:
Honestly, his quotes on the issue in the alleged texts to his mistress make this situation worse than the DesJarlais situation (you may remember that I was a huge Starrett supporter in the primary) because he pretty much said that he isn't pro-life and doesn't want his social media supporting pro-life ideas. I absolutely want him primaried, but he would still be marginally better than a liberal, pro-abortion Democrat.
He said even a hypocritical + alleged pro-life Republican like DesJarlais is better than a liberal
pro-abortion Democrat. If anything, he affirmed his status as a single issue voter.
In fact, to your question, I wouldn't be surprised if he would vote for a pro-choice Republican over a pro-life Democrat under the assumption that party leadership might force the pro-choice Republican to vote party-line on abortion stuff, and vice versa for the Democrat. Of course it doesn't always work like that irl but I don't think I've ever seen anyone as devoted to a single issue as ExtremeConservative. Every choice political choice he makes seems to be ultimately influenced by abortion.
