I live in midtown Omaha. White and wealthy neighborhood; tending to be old money and Catholic.
On my block, there was one Trump sign from an older couple. I'm assuming they have another house(s), and don't actually live there that much. They haven''t had the sign out for a few weeks, but I haven't seen them for a few weeks. Probably around 15 Biden signs.
In the 3 mile radius, I would say Biden signs outnumber Trump signs 5-1, maybe more. Almost all of the Trump signs are in yards that also have Sasse (Senate) and Bacon (House) signs. There are many yards that have a Bacon or Sasse sign, but no Trump sign. I think part of that is that Trump's NE-2 ground game is run through the Neb GOP rather than an independent office. But Biden has even less of a direct presence, and there are plenty of solo Biden signs.
And speaking of the sign war, I have to say that the variety of Biden signs are awesome. Some of them are through the campaigns, but a lot of them are just getting commissioned independently. We've got "Riding with Biden," "BYE DON 2020", "HARRIS 2020, and I guess Joe too.", "Teachers for Joe" that has an apple on it, "Vote Compassion, not Fear" - that one was from a bunch of Methodists I think, a bunch with sunglasses, "DECENCY 2020". And then there are the directly anti-Trump signs like "STD - Stop the Donald; Don't let the infection spread," "And One Day, Like a Miracle, He'll be Gone." I think the variety is great marketing. But the non-official ones also show the enthusiasm from Biden supporters to go out and seek signs online, rather than just signing up to have one dropped off.
