Thoughtomater and GilGil are far more informed on this subject than I.
just my two cents
i live in MD and work in Baltimore. (die hard liberal areas)
I have seen very few clinton signs. Even my next door neighbor(retired teacher) doesn’t have a sign up. Has had dem signs up for 16 years. The only signs i see are for Trump. This past weekend took long drive into MD country for a soccer game. Trump signs everywhere, no clinton signs.
