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.

  • Blended forecast marginR +6.7

The blend puts 15 percent of its weight on the polls and 85 percent on the fundamentals; polls take over as more arrive and election day nears.
