I'm dubious that where a candidate physically does campaign stops really matters anymore. That idea seems to be a relic of a time when news was more localized rather than nationalized. Years ago, if a candidate did a stop in Phoenix a voter in Columbus couldn't watch it or probably never heard about it. Now, you can watch that candidate's speech no matter where in the nation or even world you are.
Personally, I think Trump could have done every campaign speech from the White House while Biden did every speech from Wilmington, and we wouldn't have seen any change in the election outcome either way.
Yeah, a lot of people on here act like candidates can just pull a lever and allow themselves to win one state as long as they give up on another state.
If anything its only long-term investment that might matter more. It's not as if all those sudden campaign stops to Minnesota and New Mexico in 2016 made a difference.
