What percentage of US voters have a bumper sticker that shows support for Biden or Trump?

Answer 1

None now but many during the campaigns.

Answer 2

You can't have a Trump sticker on your car because your car will be vandalized. 

Answer 3

Not too many these days. Society has turned into an anti-protest, cancel and silence others bigot mess. You'll no doubt have your car vandalized for having a differt opinion. It was in 2015 when a local hispanic man had his truck vandalized by people he knew for having an American flag back window sticker. The stickers really started vanishing around that time. 

Answer 4

My car will last longer than any president.  Why should I deface it?

Answer 5

I still see an occasional Obama sticker, no Hillary, no Biden stickers.  I live in a broken blue state where I see a Trump sticker at least once a day.

Answer 6

Other than a window sticker with my college on it,  haven't put a bumper sticker on my car since the 80s.    No one's going to read my bumper and exclaim, "My God!  I've been looking at <insert topic here>  all wrong!.   Thank you, Mr. Subaru driver!"   

I do remember a good one from the 70s (that I didn't understand at the time).

Answer 7

I'm trying to imagine someone trying to count them. It's not working.

Answer 8

 I don't have a bumper sticker of either on mine.

Who others decorate theirs with is their decision.

Answer 9

Not sure. I'm not one of them.
