During a drive through western Maryland yesterday, I saw 14 houses with Biden yard signs or banners.
I saw 27 houses with Trump signs or banners or flags.
I saw an additional 18 houses with Trump paraphernalia and American flags. There were dozens of other houses also displaying American flags, but not a single one had any Biden signage.
UPDATE—During a drive through suburban/urban Maryland this morning I saw 23 houses with Biden yard signs or banners, and three of them also displayed American flags. I saw 11 houses with Trump signs or flags, and four of them displayed American flags.
Taking the two trips together, that’s 37 houses displaying support for Biden and 56 for Trump—in Maryland, a state that Hillary carried with a 26 % margin in 2016. I find the 3:29 ratio of American flags between Biden and Trump supporters interesting as well.
