I’ll be keeping a close eye on how quickly the cyan and pink states on the East Coast get called(New Hampshire, Virginia, Ohio) get called, as well as which swing state gets called first(propotionally, adjusting an hour or so to account for when they start counting). If Georgia or (proportionally) Arizona gets called first, that’s a strong sign for Trump. Michigan or Wisconsin(Michigan proportionally) strong sign for Harris.

Pollsters have been solid on the actual locked in voters the previous years, so this is coming down to the undecideds. Harris has a ground game edge, but the third party sphere has shifted against her compared to prior years and her shorter campaign is a bottleneck.
