That depends on the neighborhood. In suburbs with a lot of D voters you won't see a lot of Trump signs. For one thing, they have been in short supply, and for another, we avoid marking ourselves when it can lead to vandalism and other problems in the community. Look for other indicators such as flags and signs for candidates down ticket. That said, there are a lot of Biden supporters in the populous suburbs. Our job here is to mitigate damage and pray that the rest of PA can pull in enough to swamp whatever fraud the D's can pull off.
signs for candidates down ticket
