Uh, it “is” a secret ballot. How are “they” possibly going to identify “conservative vs liberal”?? I doubt they have mastered mind-reading. Just wear a BLM hat instead of a MAGA hat and you’re good.
Don’t waste money on a stupid hat, just stop by the Dems booth on the way in, get their pamphlet to wave, and thereby keep one Dem from getting that pamphlet, and so maybe they’ll vote correctly ;>
Wearing either in a polling place would be considered electioneering and forbidden.
