Gallup wasn't polling much in 1938 because of the war.There was only one poll 5 or 8 months prior to the election so we don't really know what Trumans approval ratings were
Do not underestimate President Donald John Trump. He is as clever as a fox unlike his competition who can barely speak English.
The fact you would even entertain this absurdity suggests you have no real understanding of the US virus reality. Trump obviously doesn't he filters out all news he doesn't like even if it threatens the health of US citizens.
You forgot about the 800K+ votes that were buried by the DNC! This time those votes will be counted and it won't be so "magically" close this time. Trump will see to that!
135k dead from covid (supposedly). Majority of them in deep blue cities in deep blue states. Thats a lot less democrat voters.
