Or you can be a D-leaning voter who sees D only rising to the level of a less-awful version of putting rich people before you, and you want to discipline D for taking all the D-leaning votes for granted, rather than earning them by being effective on your behalf.
Or you can be an R-leaning voter who sees both R and D as putting rich people before them, and then D goes and adds insult to injury with some stunt, but at least this one R candidate sounds like they might make things better. (Helped along by a lot of disinformation, as well as being alienated by D voters in general. You see many D voters as a bunch of elitists who're benefiting more than you, and are screwing you, while they pick causes or other people to favor that you think are stupid and unfair.)
Years ago, I was horrified, the first time I heard a D-leaning college student tell me they weren't voting D, to discipline D, in a very important election. My first thought was that this sounded like some revolutionary-till-graduation thing, which probably sounded better in their head, but now I sorta see.
Having seen a few elections and administrations since then, with D consistently seeming not to earn the votes of people, I've come around to understanding, even if I don't full agree. If many people either go out of their way to discipline D, or simply can't be bothered to go to the polls, IMHO, it's hard to blame them.
A bit similar with R voters.
We're all being served poop sandwiches, who aren't working for us, and we are desperate or depleted.
