This is a House forecast map derived from district level probabilities calculated by the 0ptimus Election Model.
The toss-up tan color is used when neither party has a 60% or higher chance of winning. Color gradients are used to show higher Democratic and Republican probabilities, deepening as the chance of winning increases: Light (60%+), Medium (75%+), Dark (90%+).
Use this map as a starting point to create and share your own 2018 House forecast. You can also view this forecast as a table.
