Diminishing returns to extremism

I don’t have something I want to talk about at length right now, but I did just realize something.

A considerable amount of the lack of compromise in politics has been driven by the belief that you have to act extremist or be thrown out of Congress or wherever by angry, motivated extremists in your own party.  At some point, elected officials are simply going to factor in that cost and accept that something like that is almost surely going to happen– in which case, they’re going to stop kissing the asses of the extremist activists.  That is, the chance of them getting re-elected are going to get low enough that they have no reason not to say what they actually think.  Then we’ll see a different kettle of fish.
