It's an example of overtly partisan issue-framing, so any factor that weighs against Republicans is amplified, and any factor that weighs against Democrats is ignored. Having said that, I do think this is stupid politics and bad policy. It hurts our credibility when we claim to care about states rights, and because the country is so divided on the issue, we're going to get wild flips in abortion laws based on who's in power. There won't be a lot of stability. There's a reason why the founders left stuff like this to the states.
