It doesn’t even have to be a large percentage. But I have met crazy left winger types that have admitted to voting Trump. My dad spent years being a left wing nutter but Pelosi made him a Republican. Sadly he died Labor Day. But impeachment, Burisma and Muslims made him change party affiliation. He was a left wing Christian. He realized Dems were the party of satan.
I think many people are going to be shocked and awed once the dust settles and the voter numbers come out. Registered Dems, Indies, blacks and Latinos are going to vote for Trump in unheard of numbers. Also non-voters.
