Nope. I spent a decade working my ass off to do that and worked my way up to being a paid campaign staffer for progressive candidates.

I suggest you do the same so that you can learn what I did: the people who control the levers of power in the party will allow progressives to be elected, it helps keep the left flank in line, but they will never allow progressives to have enough power to change the fundamental nature of the party as a machine that turns bribes into Wall St friendly legislation.
