Every single poll over the last month that I could find that meets CNN standards for reporting has shown that at least 56% of Americans want him to be barred from holding or seeking (depending on the question) federal office again.
That is, to put it mildly, a stunning percentage. At no point last year in the polling between Trump and now-President Joe Biden did Biden ever earn anywhere close to 56% in the national average.
This means that there are likely millions of Americans who voted for Trump last year who now want him barred from holding federal office.
Indeed, while about 80% of Republicans (depending on the polling) don’t want Trump being kept from running for or holding federal office, this still indicates a clear drop in support from last year. Trump won more than 90% of self-identified Republicans in last fall’s election.
