I don't see the original source (probably some dense campaign finance disclosures), but there's some numbers going around on bluesky the last day or two:
Trump's "small dollar" donations are only like 1/4 of what they were four years ago. Three different billionaires have each spent more than all the normal people combined.
The grassroots support sure seems like it has cratered, and he's being puppeted into a virtual tie by a very small number of people.
Or some sports games. Madden 2025 is almost entirely obsolete by January 2025.
