In California, polls say Rep. Adam Schiff, D-Glendale, is expected to coast to a win over Republican Steve Garvey for the state’s U.S. Senate seat. Sen. Laphonza Butler, a Democrat, was appointed to the seat last year to replace the late Sen. Dianne Feinstein.

With very few votes left to count in last week’s election, the Republican Party appears to have flipped four Senate seats—in Pennsylvania, Ohio, West Virginia, and Montana—giving it a presumptive 53–47 majority.

Political control of the Arizona Senate was on the ballot Tuesday. Six days of counting show Republicans likely to not only retain control of the 30-member chamber, but to possibly gain a seat . The Senate is currently split 16-14.
