It was common to run into not just politicians, but people working for state agencies or influential community members who were shockingly incompetent. While we did not know him, Leon Finney is a great example of the kind of wheeling and dealing I'm thinking of.
At the level we were familiar with, this wasn't a right/left paradigm (state bureaucrats are at least nominally non-partisan). It had more to do with which party had comfortable majorities, and thus offered safe career options. Our state senator is not an intelligent person. He votes along with whatever he's told to by party leadership, and struggles to articulate what's even at stake in the bills he discusses. All he knows is that if he toes the line, the party won't fund a primary challenger and he'll still have a job after the next election cycle.
