You dont see any Trump signs because they dont want their houses burned down. There is no chance that I will put one up in my yard in a suburb just west of Minneapolistan.
Ditto.
I must say after visiting in NC, I did notice about the same number of signs for each side, where we were. But I also noticed some of the Trump signs had been pulled out of the ground and were laying on the lawns. Immaturity abounds in Leftist neighborhoods.
