The Democratic campaign did no such thing. Can you point to any examples? As far as I can see they went to great lengths to avoid saying anything like that.
As far as I can tell there was far more venom from the Republicans. Maybe the lesson is that a winning strategy is to be more insulting.
Anyway, you're moving the goalposts. The allegation was "calling half the country racist sexist fascist inbred stupid genocidal monsters".
While unacceptable by presidential standards, it's extremely tame compared to the things Trump regularly says about groups of people (we could even just limit that to the things he says about liberals or Democrats), and the vocal support he receives from his supporters for these statements. The fact that this got so much attention is evidence that "double standard" would be an understatement.
Can you quote what Obama said that seems relevant to my post? I doubt he outright insulted anyone.
> And what a surprise that they went hard for Trump instead
According to an exit poll, Black voters voted 86% Democrat this year, compared to 87% at the 2020 election.

They don't (in general). Some of them over-apply those words. Some of them apply them to an over-broad category ("conservatives" or whatever). Some of them apply some of those words to some Trump supporters, which is not even the same thing as Trump voters, Republicans, or conservatives. And of that sub-sub-subset, sometimes the harsh words are even understandable, considering the hideous, immoral things they are being applied in response to.
Meanwhile, Trump supporters are much harsher with their words, and use much broader strokes when applying them.
I.e. it's the opposite. One of the defining characteristic (as opposed to simply a tendency) of the speaking style of Trump supporters is mockery and provocation and insulting and name-calling and threatening. They don't all do it, but it's an undeniable part of their ideology.
But calling Puerto Rico a pile of trash is okay?
Trump himself said Harris should be shot with 9 guns.
Somehow they still get elected.
Whether democrats finally learn that lesson is another thing. I am not optimistic on that.
