They feel secure not just due to redistricting, but after watching a man get elected who blatantly brags of unethical behavior (grabbing p**sy, anyone?) and is a know-nothing clod, most politicians probably feel rather bulletproof at this point.

They know they'll be reelected, they always are, because the electorate are stupid sheep.  That's why they do whatever they please, taking no consideration of the desires of the "constituents", hell, most of them would be hard-pressed to even spell the word, yet here they are again, the same group of miscreants burying our State in a morass of debt and poor governance.
