Probably not. There is an interesting phenomenon that has been written about from time to time about "internal" lobbying on Capital Hill. We hear about corporate lobbyists constantly during campaigns, but we rarely hear about the robust lobbying efforts that are conducted by each funded agency. No agency wants their budget to be smaller than the previous year's, so they spend massive effort convincing Congress that they aren't wasting money. I'm sure "jobs" is one of those rallying cries. Also DHS has a special place in hell, because if a Congressperson voted to cut its funding and an attack happened (whether or not DHA could have prevented the attack with the higher budget), then that person would be voted out of office in a millisecond. Because people are easily manipulated.Is there any way to get rid of them?
I think your last point is salient, in the same way that it's hard for any legislator to run on a platform to relax prison sentences--no matter how over incarcerated and racist a system is--because it's so easy for an opponent to play on fear. If the TSA continue on this road of mismanagement and long lines, maybe people would get fed up enough for something to happen. That's a really cynical way to look at it. Or way-too-optimistic, to those who think we'll never be rid of the TSA.
