“Signs are pretty meaningless. The parties send out hordes of volunteers who put them out like pink flamingos. They might be good for name recognition in a Senate battle, but for POTUS I just think they are a waste of paper and money.”

I agree with the basis for your statement, but there is no basis for seeing, in this case, a 3-4 to 1, Trump to Biden sign advantage in a HISTORICALLY STRONG DEMOrat area such as the Scranton-Mid Valley area of Pa this cycle.
Only thing I can think is that the left has WAY overplayed their hand with law&order, immigration, and downplaying this economy. Just my best guess
Based on my local observations (Democrat block captains strongarming and people afraid to post Trump signs) more than a few people who have Biden signs in their yard are actually going to vote for Trump.
