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.
The perfect reason there should be term limits -— whether by law, or self-imposed until then!!!
