We could if the left would punish their own.
Actually, it doesn't require the help of ANY politician.
We can purge DC of the professional politician... return to the idea of the citizen-politician... and thereby break the power-and-corruption cycle... all by ourselves. And it is crucial to our survival that we do. As 9/11 demonstrated, self-serving, mediocre, abject losers in positions of leadership can be fatal.
We must field citizen-politicians of the highest caliber. As envisioned by the founders, the citizen-politicians would ''lend'' their expertise to government and then return to private life. The culture of access, influence and self-interest--and with it, the tyranny--would literally disappear overnight.
With their obvious excellence and assisted by the new technology, the citizen-politicians would easily bypass the stacked system to capture the imagination -- and the votes -- of the masses.
