It's really simple: Donald Trump was elected by less than 2,000 votes across 3 states in 2016. It was a hairline. It was a fluke that nearly didn't happen. And he spent the last four years belligerently insulting people in the cities and suburbs he needed to win again. Now he's lost by 12,000 - 50,000 vote margins in each of 7 states.
He brought it in himself: his popularity has gone nowhere but down in four years. Now he's unelectable.
You think he's won? Prove it! The numbers are not on your side!
