Ive noticed in my area the only signs left out are Conservative ones. To be clear, they arent the ones put out by the candidate but are being left out by homeowners. No other party’s signs are still out.
Is this a thing Im just not aware of since I dont travel in conservative circles very much or is it just a big coincidence.
Typically, the local campaign picks up the signs so the person living there doesn’t have to deal with it (and so they can be reused in the next election).
It sounds like whoever ran the Conservative campaign in your area hasn’t organized proper sign retrieval yet. Maybe the sign volunteers ghosted them, maybe the sign lead flaked out, or whatever.
