Just because I can point to a few examples of how things aren't worse, doesn't mean there aren't still things happening. Biden or Trump, the Supreme Court's makeup wouldn't be different – Ketanji Brown Jackson wouldn't be on the court, but she only replaced another liberal who otherwise could have held on another 4-8 years I think. These rulings would have happened no matter who was President, but they'd be in addition to everything else the Trump Administration does on its own (and I don't even mean kids in cages, since that's still a thing, I mean things like how he wants to be able to directly control most government agencies and fire public sector workers personally).

The way I see things, it's a sound political strategy for leftists to vote for someone like Biden and then use his liberal failures while in power to further radicalise people. IE, "yeah, he's not gonna sign a national abortion ban or attack Critical Race Theory, but he also won't expand the Supreme Court in order to protect these positions in the future". I'd rather radicalise people by pointing out the failures of a liberal than by defending me and my friend's literal existence from a fascist weaponizing every government agency against me.
