I think biden is actually an extremist in social policy, and an emboldend corporate shill in economic policy. So while he might be "milquetoast" in terms of democrat vs republican, he's far from what regular people want/need.
Ironically, most establishment republicans are also this way. They're happy to push insane social policy stuff, while bootlicking the corporations.
I honestly think that the GOP will probably split or collapse due to the establishment GOP's resistance to their populist voterbase. Democrats call it 'unhinged' but when informal polls show literally hitler as preferable by both left and right to biden/trump, I would say that both dnc/gop are the unhinged ones, not the people sick of the two parties.
"milquetoast" is the literal polar opposite of what we need right now.
