I don't really trust Republicans or Democrats, to be honest.

Wise observation. Good thing 2016 happened. At least one group got cleaned up since then.

Which group was that?

Republicans have been cleaned out.

Here's a Very old List. It's gotten a lot bigger and it's still republican dominated:

"List of politicians not seeking re-election
Bob Corker, R
Charlie Dent, R
Jeff Flake, R
John Duncan, R
Bob Goodlatte, R
Jeb Hensarling, R
Lynn Jenkins, R
Sam Johnson, R
Frank LoBiondo, R
Tim Murphy, R
Ted Poe, R
Dave Reichert, R
Ileana Ros-Lehtinen, R
Lamar Smith, R
Pat Tiberi, R
Dave Trott, R
Carol Shea-Porter, D
Gene Green, D
Joe Barton, R
John Delaney, D
Luis V. Gutierrez, D
Niki Tsongas, D
John Conyers, D
Sandy Levin, D"

Okay.
