we can’t fix our current situation in one election.
We can never fix the current situation in one election. Fixing the American system, within the parameters set forth by that system, requires a dedicated voting bloc that lasts multiple elections refusing to vote for the Dems until they shift far enough left to appease that bloc. As long as you are focused on the next election, your prescription for fixing American politics is just as unrealistic as a random Twitter tankie declaring a general strike.
Tankies are very frequently the only people in the room who’ve done the reading. If you believe that so called “authoritarian methods” are antithetical to leftism, then I recommend you read the following pamphlet by Engels.
