In my local travels, one of the largest and most expensive homes has a giant "Biden/Harris" sign on their acreage.
About a dozen more modest homes have "Trump/Pence" signs on their front lawns.
Of course, most homes do not have any political candidate signage, or any other markers to indicate a preference. That seems prudent to me.
Our neighbors have back to back properties. We noticed one has a HUGE Biden Harris sign. The other has huge TRUMP signs. I bet they are not friends!
