The costume math checks out for JD Vance: beard and white hair already on deck, so Dumbledore from Harry Potter was the call. Kid-driven decision, obviously. His four young children are deep into the series, and he says Halloween with little ones is a lot of fun. Last year's pick was Fat JD, and this one lands in the same self-aware lane. He told Fox News the resemblance makes the whole thing feel very comfortable. Say what you want about the guy, picking his outfit around what his kids love is elite parent behavior, girl dad and boy dad both.
