Honestly that’s overselling Biden and their own pitch is you are voting against ending democracy. Biden isn’t going to make the future less grim (unless we protest), but Trump would certainly make it worse.
He absolutely is making the future less grim. The industry news I read for my work in the energy industry is full of progress in environmental regulation. It’s a fight vs Republicans and Biden is really making progress.
What progress will you have to make if Biden who has been polling 40/40 or 39/41 loses to Trump? It may be less grim (if he can win) but it is much more likely to be grim if Democrats don’t take their heads out of the sand and consider nominating someone actually able to handle a debate against Trump.
