Many people here like polls (and election results) when they support their position. However, they claim that they are corrupt when they do not. Some are corrupt. Most just give an imperfect window into the collective American mindset at a particular instant in time. Consider accordingly.
And in this case, in a particular small area.
If you polled my small area, Trump would lose hugely, definitely the general, and likely the primary.
Poll some “red” state region where hardly anyone would have a virtue-signalling yard sign, and Trump would probably win big.
