I'm thinking that even though it's incredible unlikely, and you're right that their true beliefs and actions are antithetical to progressive values, the Dems are at least symbolically tethered to a progressive image that I think leads to the possibility of the party being bent through external forces such as an organized left. I see no such possibility from a Republican administration. This is purely a take about the possibility of reform, and I do realize that it's still incredibly unlikely under a Biden admin for anything positive to happen. I think it's just slightly more likely than under a Republican one.
