I've been asked who I'm voting for by complete strangers. If they're wearing hitlary or bernie gear, then that's who I'm for.
If they're wearing Trump gear, they usually get a big smile and a fist bump.
If I can't tell, I say my vote is my business and no one else's. (Although, the 3 NRA stickers I have on my truck should be a clue).
I find it easier to deal with the enemy by simply agreeing with them, rather than getting into a pissing contest wherever we happen to be. I'm non-confrontational by nature and hate to fight/argue.
