I agree, but living in the south I can tell you that my personal observation (non-statistical) is that the ones still flying Trump 2020 flags also seem to be the last in line to get the jab (supported only by word of mouth of health care workers I interact with).
As sad as it sounds, it's like it takes someone close to them checking out from it to convince them "it could happen to me". At any rate, the more people vaccinated the better for all of us, regardless of political beliefs or alignment.
As a side note, one particular amusing observation I had the fortune of making. While driving through a rural area I came up on a beat up truck with the following spray painted freehand on the tailgate "Fuck Biden and fuck you to for voting for him". I wanted to follow him to inform him he meant "too" not "to" and ask how he knew who everyone he saw on the road voted for but I've seen deliverance and rolled on.
