Not a poll, and certainly not scientific, but out of curiosity I drove around my neighborhood to count political signs. I broke it down into 6 categories: (1) homes with Harris signs, (2) homes with Trump signs, (3) homes with no signs for presidential candidates but with signs for other down ballot Dem candidates, (4) homes with no signs for presidential candidates but signs for other down ballot Pub candidates, (5) homes with no signs for presidential candidates but signs for candidates from both major parties, and (6) homes with signs for third party candidates only.
As for demographics of this neighborhood, it is in Charlotte. It is in the southeastern section of Charlotte, but is also pretty centrally located. It is very white. Almost all of the homeowners have a college degree, and a fairly large percentage likely have graduate degrees. I believe there are two precincts that cover this neighborhood, and they both went blue in the two previous presidential elections in which Trump was a candidate, with one being much bluer than the other (all but two precincts in all of Charlotte went blue in 2020).
First of all, the vast majority of homes— hundreds of them— have no political signs.
No homes have any signs for third party candidates and no homes have signs for candidates from both parties.
31 homes have Harris signs.
7 homes have Trump signs.
38 homes have signs for democratic candidates, but no signs for presidential candidates.
Only 2 homes have signs for republican candidates, but no signs for presidential candidates.
There is one house where the only political sign is an anti-Trump sign, which doesn’t necessarily fit into any of the 6 categories I came up with.
