Alex Thompson informs me today that Kamala Harris no longer supports Medicare for All; says she won’t ban fracking; wants to increase funding for the border; and doesn’t want to require people to sell their assault weapons back to the government. Obviously this means that Harris has wisely decided to shift a bit toward the center now that she's in a general election contest for the presidency. That's pretty standard triangulating.
But it probably doesn't matter all that much. This is policy stuff, and most voters care about policy only in the broadest terms: for or against abortion, pro or anti gay marriage, and so forth. What they care about a lot more are social values, and even that's mostly on the level of vibes.
This is what J.D. Vance was getting at with his oddball comment about "childless cat ladies." He was using that as a metaphor for lefty women who like to spoil everyone's fun by harrumphing about racism and mass transit and single-use plastic bags. Obviously Vance chose his metaphor badly, but the point he was making is very, very common on the right. They believe that liberals aren't just wrong, but really annoying.
And often we are! This is where Harris would also be wise to shift slightly to the center. Not a lot. Lefty values are more popular than conservatives like to admit. But it wouldn't hurt to make some noises about the evidence on gender affirming care being unsettled. Or that, yes, DEI training can sometimes be a bit on the ridiculous side. Or that the Bible is the word of God (which she presumably believes, being a Baptist and all).
These are the kinds of things that can make centrist voters more comfortable without really ceding anything that's of concrete value to the liberal project. It's basically just a way of putting across the idea that she's a normie, not a nutball extremist. And it draws a contrast with Trump and Vance, who are nutball extremists.
Mock Bill Clinton's Sister Souljah moment all you want, but it worked—and since the liberal coalition isn't in favor of killing white people it didn't concede anything of value. A little bit of this goes a long way, especially if it comes as a bit of surprise and gets some press.
