Where the outside money came from
For the biggest spenders, the money is followed upstream while a single donor supplied at least half of it. From FEC receipts.
- WinSenate ← $21.1M from SMP (95% of its reported receipts) No donor disclosure
- The Maine Standard ← $8.7M from SLF PAC (100% of its reported receipts) ← whose largest donor is Elon Musk, $158.0M
