My question is how does anybody know how someone votes in a general election? You don’t declare anything publicly in a general election. It isn’t a primary where you have to declare party affiliation to vote on one side of the political spectrum or the other.
how many people will vote for Trump but will proclaim their support for Biden before and after they cast their vote because their peer group demands that everyone be against Trump?
I bet there are lots of people in this position, and I wonder what we should call such people, perhaps “the hidden silent majority”
