Outside groups: 24- and 48-hour independent expenditure reports for the 2026 primary and general, through 2026-11-13, each expenditure counted once after amendments; "ads" is TV, radio, digital and other media, and the rest is mail, phones, canvassing and similar. Campaign's own ads: TV, radio, digital, other media and ad production in the campaign committee's itemized payments, as the campaign described them, from the reports the FEC has processed (latest through 2026-09-30); newer reports appear as the FEC processes them. These are amounts committees reported paying, not airtime tracked by ad-monitoring firms, so very recent buys and future reservations may not show yet. Parser fec-ad-spend-1.0.0.

The four Vugol signals, side by side
They answer different questions and are kept apart. Full method: Methodology.
- Vugol Vector
- Our call for every race if today’s polls hold. A snapshot, not a win probability or a vote share.
- Vugol Tensor
- How sure we are: ranges and chamber-control odds around the Vector, built from past polling error. An experiment about uncertainty, not a better guess.
- Vugol Attention
- How much news and online noise a race gets, 0 to 100. It measures noise, not support: a high score says nothing about who is ahead.
- Vugol Pulse
- Our daily thumbs-up or thumbs-down question for readers. Anyone can answer, so it describes our readers, not the public. It is not a vote and never enters a poll average or any other signal.
