If you're agreeing with ameancow's suggestion that the solution is to primary non-progressive democrats, that's not how we seize our power as the working class imo. The Democrats rigged their primaries against Bernie Sanders then had a court declare they were legally within their right to do so.

"[The DNC] could have voluntarily decided that, Look, we're gonna go into back rooms like they used to and smoke cigars and pick the candidate that way. That's not the way it was done. But they could have. And that would have also been their right..." - DNC attorney Bruce Spiva

You are trying to play democracy with a fundamentally undemocratic institution, according to their own legal claims. And even if you win, they're excellent at corrupting people - just look at AOC Pelosi voting to fund the Zionazi entity.

On the other hand, you're totally right that we have the real power in this country as the working class. Electoral politics - especially on the federal level - just aren't how we're going to effectively exercise that power. I vote anyway, it's not a difficult thing to do, so why not? But I'm not under the illusion that it will save us. We have to hit them in the only place they care about: their wallets, bank accounts, stock portfolios, and GDP.
