To my knowledge, each US legislator is selected by plurality/FPTP except the senators from Maine and Alaska who are selected by RCV. Note that Trump was able to remove critics by having them "primaried out" against MAGA challengers.

You just vote for a single party (closed list) or politician (open list), and the seats are then allocated by votes won. That's it.
This is *far* preferable to a minority running roughshod over the preferences of everybody else, like what's going on here right now. (2/2)

Smaller parties have to *hope* a larger party invites them into a coalition, and the more seats they have (and fewer demands they make), the better chance they have.
The largest party gets to do the inviting.
