The following ratings are final, barring exceptional and unanticipated late–breaking news.
Races outside of the violet and red lines are considered a safe bet for Democrats and Republicans, respectively.
Races inside of the yellow and green lines could reasonably be expected to go for either party on Election Night. The white line indicates the current best guess as to the final result.
Races between the green and blue lines lean towards the Democratic candidate, but a Republican upset would not be particularly surprising. The same is true in reverse for races between the orange and yellow lines.
