FTP Race Signal

FTP Race SignalA composite of market, polling and money. The prediction-market price anchors it; a polling average moves it: the last 30 days, or the three most recent pollsters when fewer polled. Polls paid for by a candidate, party or allied group move 2 points toward the other side and count half. When the three most recent independent pollsters each have the race within three points, it is a Toss-up unless the market is already decisive. Fundraising counts only at a five-to-one gap. Past results are context, not inputs. A rating changes only when the evidence clears the line.

This district was redrawn in August 2025; the 2024 result on the previous lines does not describe it. The market prices the new seat at 96.5¢ Democratic.
