Quite the contrary, after my initial low-key contact, I didn't say a thing to him. Meanwhile he was walking in another aisle parallel to me in the parking lot apologetically blabbering the whole time. The only thing I really did after my initial comment was to hold my cell phone up to get the second photo of him and his car.
BTW, next time I see suspicious vote registration activity, I will first go home and return with my GoPro camera to record it on good quality video.
You were stalking him and taking photos. Kinda weird, yes? Plus you approached him and acted up about his Hillary sticker. What if a Hillary supporter did that to a person registering voters for Trump? Your behavior was unusual and to him it wasn’t worth talking with you further since it might have turned out badly.
keep the go pro in your glove box when you travel
of use phone pretend you are talking to someone while video taping
