The wingnut welfare machine takes care of its own, but as with all things in modern American conservatism there’s a quid pro quo. In order to land post-Congress gigs (speaking engagements, book deals, media pundit spots, appointments at fake universities, think tank positions, board seats, etc.) amounting to about $1-million a year they first have to stay in office long enough to deliver billions in tax breaks and other goodies for America’s wealthy human and corporate persons.
One or two terms isn’t going to do it, and once they’ve been in office long enough to accomplish that the antes are upped such that they have to stay in or lose everything.
Which is an example of the fundamental way that America’s economy is a terrible place for everyone.
