In Phoenix I am seeing no bumper stickers of any kind! I think polling is really suspect this season. There are a boatload of people who are embarrassed to admit supporting their candidate. This goes for both parties.
The relentless hammering from the MSM makes Trump supporters hesitant to admit their support. However, there are also a lot of Hillary supporters who are ashamed that they will mark the ballot for such an obviously ethically flawed candidate.
We live in suburban Columbus Oh, and have honestly not seen one Trump bumper sticker or sign, but have seen Hillary bumper stickers. Yesterday we went into a downtown Columbus area, called the “short north” “arena district”, “ Victorian Village”. It is located between downtown and OSU campus, very trendy, young, expensive and upscale. Hillary signs everywhere, house after house. One street had LGBT for Hillary on most of the windows. My head was exploding!
Here in south Virginia, I see more and more Trump signs, but not yet a SINGLE Hillary sign. Not sure how it is elsewhere.
One of my friends put a Trump bumber sticker on her car. It just so happened that she began to get sabotaged at work. Might be a coincidence, but I wonder.
