of the president's cult causing them to lose their jobs. Being a member of Congress has become such a cushy gig that a lot of members would sell their souls to keep it. The founders did not intend congress to be a permanent, full-time job - they envisioned citizen legislators who would spend a few years in their positions and then return to their previous work. Unfortunately that idea didn't stick, and being in congress became so desirable (and ultimately profitable; if they ever left they could get lucrative jobs as lobbyists, and if they didn't leave they could just do insider trading and take kickbacks that aren't technically bribes). You almost have to be rich even to run for federal office any more. Since they aren't "citizen legislators" but permanent full-time office-holders who want to keep their jobs at any cost, they dare not upset the MAGA cult and face a primary.
