Did Bernie Sanders ruin the possibility for mass movements to manifest in the near future?

I can't help but wonder if the presence of a Democrat in the presidency just sort of pacifies liberal, left, and radical mass movements and mobilization.

This seems to always happen. It takes until the last half of a Democrat president’s second term for the left to mobilize enough to become a movement that puts pressure on the dems. Happened with Clinton and Obama. I would expect some type of growing and perceptible left movement in the last couple years of Biden’s second term.

And when the GOP is in power the left gets used by liberals as street pressure for their own goals by using their power as libs to access media and finances to organize people to “resist” The GOP and the left goes along thinking everyone is fighting for their goals but in reality the liberals just use them to further their own agenda and leave the left to suffer the consequences of trying to actually change things and not just get liberals back into power.

Mass politics in America is a sick game.
