This is simple. If everyone that supports Trump goes out and votes then he wins almost every state. If they stay home because they do not believe he can win, or because they are too busy, or believe he doesn’t need their vote because their neighbor is voting Trump, then he loses.
We have the votes it is all about tournout. Call your friends and neighbors and make sure they have voted.
In our case my wife and I just started calling, offering to take them to the polls, run an errand so they can go vote, and anything else in reason to get people to the polls.
Deplorables over the wall!
