John Oliver expects them to be at the local level:
Betsy Woodruff also spotlights the state races:
If there’s one truth of divided government, it’s that the most significant legislative action often happens on the state level instead of in gridlocked Washington. While the U.S. Congress has been bogged down in a morass, state legislatures with single-party rule have been hopping. In the last few years, for instance, the Republicans who control Texas’ legislature and governorship have passed bills banning abortion after 20 weeks, tightening regulations on abortion clinics, reducing the number of required standardized tests for students, running the table on tort reform, and requiring photo ID to vote.
And just like Republicans running for federal office are expecting a wave or wavelet of sorts next week, their state-level counterparts are aiming to take control of a few more legislative chambers—potentially with substantial policy consequences.
Carl Klarner’s forecasts that “Democrats will lose majorities in five state Senates and nine state Houses”:
Those state Senates are Colorado, Iowa, Maine, New York and Washington, while the state Houses are Colorado, Kentucky, Maine, Minnesota, Nevada, New Hampshire, New Mexico, Washington and West Virginia. … Forty-five states will have elections to their state legislatures this coming Tuesday, although four of those states do not have elections to their state Senates (not including special elections). Democrats are likely to lose seats in most states. The only gains are forecast to come in the Oregon, North Dakota, and Rhode Island State Senates, as well as the North Dakota House. West Virginia is forecast to see especially large losses for the Democrats in both of its chambers. Other states will see losses for the Democrats of over 10 percent, including the California Senate, the Nevada House, and both chambers of the Maine legislature.
