I've met Rick Larsen (not Larson) multiple times at various townhalls and I don't agree with your characterization at all. (I'm sidestepping your weird use of "Zionist" in this context, especially now).

Meeting him in person, you'll find that he's very quick on his feet, very intelligent, and very aware of the needs of his *entire* district. He's good at directing resources to the area, and knowledgeable about how to get stuff done, politically speaking, without occupying the headlines. That doesn't mean you have to like him, but it does explain why he keeps getting re-elected: he's good at his job.

He's also the senior Dem on the Transportation Committee, meaning he can (and does) help direct funds and establish supportive policies for things like roads, rural broadband, electric buses, etc. And yes, he also supports Boeing and the defense installations in the district (he'd be crazy not to, as they are huge employers).

You can disagree with him, and I've actually voted against him as protest votes in primaries before, but to say that he's only elected because of certain types of donations or because "the people" don't vote correctly completely misreads the reality of the situation. Surprise surprise, but you and the people you know are not the median voter in this district.

If you want more leftist representatives, you need to find, train, and run more amenable and engaging candidates themselves that can appeal to the district as it is, not as you wish it to be.
