They might surprise us with some protestors and half empty field house.

T: less than 5000

H: greater than 19,000

any takers?

They'll cram everyone who shows up in Bozeman into one section of bleachers to make it look packed.

There are actually more people living there than I thought, over 50,000 in the town, 118,000 in the county.
Glendale, Arizona has 250,000, but is in the Phoenix metro area, with about 5 million people. Which place provides the better opportunity for the exposure to undecided voters and more electoral votes?

But then, Biden won Gallatin County, where Bozeman is located, in 2020, by almost nine points. So 5,000 for him is probably a good guess.

The next place to go would be a stadium.
