One other use of political symbols such as bumper stickers or flags etc is to "mark your territory" to make sure that people know whether they are welcome or not.

As an Irishman driving through some parts of Northern Ireland the best/worst case of that was some small towns and villages that more or less literally, had every available space covered in the British flag. I mean every building and many windows had a flag on or it it, every lamppost was covered in both flags and bunting of even more flags. It looked like there was some sort of British flag bomb that had coated the town.

Do you think me with my Irish reg car, and Irish accent stopped in that town while I was driving through?
