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.
