What cities did he lose in 2020 that he won in 2016?
And strangely you seem to totally discount the FRAUD that anyone with a brain stem knows happened. Trump INCREASED his vote totals among all demographic groups and his victory absent the fraud would have been monumental.
There is no point in discussing the reasons Trump lost since absent the fraud he didn’t and the fact remains he got more votes than any incumbent in history.
Trump didn’t loses in the Cities vs 2016.
He lost in the suburbs of the Large cities, where the Single/Divorced women live and turned out to vote overwhelmingly against him. I live in a affluent suburb and I saw them. Everybody saw them. I have relatives that were them. TDS was strongest in these women. They though their vote was saving the world.
Ballot Harvesting was a way bigger factor than “fraud”, but universally pissing off single/divorced women in the suburbs was a bigger factor than either.
