Left: what the group raised, from reports through Oct. 14, 2026. Donors are its largest single contributions. “Everyone else” is the rest of what it raised; select it to see more donors. Right: its outside spending through Oct. 30, 2026, including 24- and 48-hour reports. The two sides come from different reports, so they don’t add up to each other.

Where its money went

  • Given: the group’s own contributions to the campaign
