Carefully structured polling, with massive oversampling of Democrat voters by calling when the entitlement class is home and the working class is...working.
I have found that a lot of folks who will vote for Trump don’t care to mention it in “polite circles”.
My view is that Trump actual votes will consistently exceed polling numbers.
Run out like rabid dogs to vote for an unreformed criminal and incompetent bureaucrat. That sounds like a democrat city dweller.
