Democratic Rep. Ruben Gallego is projected to beat Republican rabble-rouser Kari Lake in the race to become Arizona’s next U.S. senator after Lake seemed to struggle to win over moderate and independent voters.

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.
