IF Trump wins Wisconsin he is reelected. Simple is that!
Trump can lose MI & PA which he probably will.
However if he keeps Arizona, Florida, Georgia, North Carolina, Ohio, Iowa and those 2 Districts in Nebraska & Maine he gets 270 Electoral Votes to 268 Electoral Votes.
The polls consistently show Michigan and Pennsylvania as nearly-certain losses for him. Colorado, Maine at-large, Minnesota, Nevada, New Hampshire, and Virginia are seemingly spiraling out of reach. With one of ME-01 and NE-02 but losing nothing more from 2016 to 2020 except Michigan and Pennsylvania, Trump wins because House delegations will decide... and on this, one Congressional Representative from Wyoming means as much than 53 from California. If Democrats should get a majority of House delegations, then they are winning the Presidency in a landslide.
Trump wins Iowa and Ohio, both of which he must win to have a chance of re-election, if he wins Wisconsin. He must still not lose one of Arizona, Florida, Georgia, and North Carolina, and not both of the Second Congressional Districts of Maine and Nebraska if he is to win.
