I too would wish he’d expand the court as he suggested he would on the campaign trail, but unfortunately the game of politics is such that actually doing it would become the biggest topic ever, and not in a good way. It would be super unpopular with the moderates, and it would allow republicans the perfect opportunity to accuse Biden of being anti-democracy, which of course they would love an excuse to do because it would distract from the fact that they actually want to destroy democracy. Maybe, and this is a big maybe, he’ll consider it in a second term when he no longer has to worry about re-election, but that hope always seems to be a pipe dream.
