I've discussed the TSA with my US Rep, but there just wasn't the political will to make the TSA an issue. Written communication there gets handled in the usual way, serving even less utility than waiting to be seated next to my US Rep on yet another flight, running into the person at a farmers market on some weekends, or meeting up at some social gathering.
My written communications to one of my US Senators usually get a form letter or occasionally a personal response (depends on when/how handled), but the other US Senator just barrages me with unrelated junk mail and no responses to the issue whatsoever. In person, neither is willing to do more than just listen and nod their heads in a sort of "ok, whatever" way. The US House member does more than that, even agrees in part, but has bid adieu to the notion that this work of the people is enjoyable, necessary, or even tolerable.
I'm pretty confident that all three of my elected members of the US Congress sort of still believe in the "to professionalize, federalize" belief.
