That may very well be true for those currently camped out in Washington, but it is absolutely NOT true for everyone running now. I know I personally want to try to make people listen and make the changes we need. The problem is getting traction when the establishment guy has been there for 20 years!!!
I don’t doubt that many that run for any political office run for altruistic reason, but once in any political office things begin to change. I have watched many with the purest of intents become political whores and succumb to the lure of power and prestige of political position.
Hard to ignore the glitter, pomp and circumstance that goes with political office.
