Few on the left are expecting Biden to do much other than try to make back some ground lost. The vote was almost literally "Would you like Trump or just some guy who doesn't do what Trump does" and the latter won.
Perhaps not here, but make no mistake a large portion of the left are mentally unstable people who blame Donald Trump for every wrong in their life. Just wait until Joe is dropping bombs on some brown people have a world away...
Just consider the reaction to Dick Cheney being named a national security advisor. Was it your guys plan to elect the bush NS team?
