I think it should be more concerning Trump has opened up very few campaign offices even in the main swing states.
Campaign offices aren’t part of the TRUMP campaign priorities. Campaign offices are a Bill Clinton-era holdover, aka something consultants have convinced campaign managers are necessary without much proof of their usefulness at the presidential level.
TRUMP is dominating earned media, meeting voters where they are. And that’s social media for young people and cable news for old people. Biden is hoping his pre-internet campaign can squeeze out enough college-educated women, but again, he’s relying on old campaign tactics.
Campaign offices play a key role in ground campaign which I would argue is still very important today - even with modern technologies and mass media. In 2020 for instance, there were clear consequences of not having ground campaigns, especially in black communities in key states which were some of the only communities to see turnout declines 2016-->2020.
