Trump is already deeply unpopular in NYC, so it’s not likely to change anything on the national stage. New Yorkers have been seeing Trump’s BS on parade for decades now. It won’t change New York’s opinion of Trump.

Nationally, it might. But that’s only if the media actually runs with it; The big news orgs are all in bed with the established politicians, so they’ll likely be smearing him left and right to avoid having it turn into a national shift.
