well sorta. Clearly americans right now want a big shouty man full of p/ss and vinegar, making loud pronouncements in the news every night. Joe can't do that. So it's his fault sorta.
Honesstly, I've said on this thread many times that biden is not a great comforter of a president. He's not good at talking to the American people. He's a manager, a technocrat, a guy who hires really well and works quietly. It's fine with me, but clearly the country wants a bigger personality.
I think the country is in some kind of crisis and this kind of polling shows that.
although you have to keep in mind a lot of the dissatisfaction showing up in biden polls is AOC types furious that biden won't break rules to get things done. They'll still vote D but don't like Biden Dems because they want more fighty lefties in office. There was no such issue with Trump - he had the full support and backing of the Republican voters. In the palm of his (small) hand.
