Over time
How the forecast has moved
The margin
How close it lands
Each simulation produces a final margin. The curve shows where those margins fall; the tinted areas on either side of even are the futures each party wins.
Under the hood
What's driving the number
The forecast blends a weighted poll average with a fundamentals model: the state's partisan lean, incumbency, the national environment, and fundraising. Positive points favor the Democratic side of the margin; negative favor the Republican side.
- Partisan leanR +19.0
- IncumbencyEven
- National environmentD +5.1
- FundraisingR +1.5
- Fundamentals sayR +15.5
- The polls sayR +26.0
- Blended forecast marginR +17.7
The blend puts 21 percent of its weight on the polls and 79 percent on the fundamentals; polls take over as more arrive and election day nears.

The evidence
The polls, as the model sees them
Every public poll of this race, with the weight the model gave it in the latest run. Weights reward recency, sample size, and pollster track record; the house adjustment corrects each pollster's habitual lean before averaging.
