I’m not sure I follow your first point? His margin in Michigan is more than Biden won the electoral college? What does that mean? So Trump won Michigan by around 82k votes. Yes 82,000 is a bigger number than 306- the EVs Biden won?
Anyway, Biden wasn’t a landslide either. The last landslide would have been Obama’s election in 2008. Not even his 2012 win was a landslide. And it was by a bigger margin than this. Once all the votes are counted I don’t even think it will be more than half a percent difference in popular vote and he might not have even won the popular vote. Which of course doesn’t matter for the election, but certainly is relevant to whether the election wss a blowout. Bottom line, it came to the 8 states we thought it would and right now it looks like Trump won them on average by 1-2 pts.
He won fair and square, but to perpetuate the myth that this wasn’t close now is just too much.
