Why we think this
- This state's baseline partisan lean favors Democrats by about 8 points of margin before anything else is considered.
- This is an open seat: the current officeholder (a Democrat) is not on the ballot, which tends to make the race more competitive than a defended seat.
- Independently, the national midterm environment is shifting every race this cycle significantly toward Democrats -- a separate, nationwide force layered on top of the state-specific factors above, not a restatement of them.
