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 +10.4
  • IncumbencyR +1.0
  • National environmentD +5.1
  • FundraisingD +0.6
  • Fundamentals sayR +5.7
  • The polls sayD +5.7
  • Blended forecast marginR +1.4

The blend puts 37 percent of its weight on the polls and 63 percent on the fundamentals; polls take over as more arrive and election day nears.
