No. It is that Trump won with the support of over 70 million Americans. People are responsible for their choices. jfc
Everyone saying Trumps totals didn't change, yes, but their composition absolutely did change. But even that is besides the point. Even if they staged exactly the same, that's still really fucking problematic and its absurd to give these people cover for being shitasses.
So really the change between 2020 and 2024 is not a popularity increase for Trump, but a huge popularity loss for Biden/Harris.
Now the question is, how did Biden/Harris manage to be so unpopular, that 12 million people decided to rather risk Trump winning, than vote for them again?
