In general, Indiana is deep red.
I drove from the very my home just outside of of the mixed red/blue town of Terre Haute through very red Indiana counties to relatively nearby but not inside the mixed red/blue town of Bloomington (more blue than red there). In both cases, not in the towns, so essentially from Republican territory through Republican territory and ending in Republican territory.
I only saw three Harris signs, which didn’t surprise me… but I only saw two Trump signs, one of which I know has been up for months.
Even houses with things like those stupid thin blue line flags on flagpoles didn’t have Trump signs.
On top of that, neighbors of mine who I remember having Trump signs the last two times around do not have them this time. I live in a massive subdivision- probably 70 homes- and I have only seen one Trump sign while walking or driving through it.
Make of that what you will.
