Tell me again about how this applies to a candidate showdown like James Talarico versus Ken Paxton.

> There's no such thing as people voting against their own interests.

This is truly as nonsensical opinion as people always choose healthy choices. People can absolutely make self destructive choices. A smoker choosing to smoke isn't making a good choice, but to you they couldn't possibly choose something against their interests. It would be in their interests to stop smoking, but they're unable or unwilling to make that decision.
