“There are only so many endorsements you can get from powerful establishment
politicians and the rich and famous before you’re no longer a credible agent of change
(for all but the most gullible). Obama passed that number some time ago.”

Isn’t that Xeno’s paradox? You can’t get elected without getting a plurality of the votes, but long before you get a plurality of votes you’ve become an establishment figure?

I guess I’d better give up then, because you’ve proven that change is fundamentally impossible.
