There are some other things transpiring in American politics right now. But we must note that Democratic leaders are now unabashedly stating what Bernie Sanders supporters said over and over in 2020: the party pushed Joe Biden primarily to stop Bernie.
That I agree with. Any certainty he would have won in red states is misplaced though, elections are not that predictable. He might have. He might not have. He certainly wouldn’t have gained support from anti-communist types though, and that line of attack would have been employed heavily by the repubs. They do it anyway even with neolib dems.
