electoralism

so why stick around? There are very few jobs I can imagine wanting to do until the day I die.

My guess is that it's the sweetest gig imaginable where everything is done by your army of staffers and interns and people immediately surrounding you do nothing but kiss your ass. You just have to occasionally sign a bunch of tl;dr document and appear in the public every once in a while. And they're still getting paid even when Congress is not in session.
