Over time
How the forecast has moved
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 leanD +15.8
- IncumbencyD +2.5
- National environmentD +5.1
- Fundraising *Even
- Fundamentals sayD +23.3
- Blended forecast marginD +23.3
With no usable polling, the forecast rests entirely on the fundamentals. * Source data unavailable for this factor, so it counts as neutral.
