Who Will Control the US Senate? Katherine Gypson WASHINGTON - Control of the U.S.Senate remained uncertain early Wednesday as a handful of races in states including North Carolina, Maine and Georgia remained too close to call. In Colorado, Democrats made a key pickup when Republican incumbent Cory Gardner lost to Democratic challenger John Hickenlooper, the former governor. Gardner is the last remaining Republican statewide official in a state that was once considered an election battleground. According to the non-partisan Cook Political Report, just seven of the 35 Senate seats up for election Tuesday were rated true toss-ups. Senate Republicans went into Tuesday holding a 53-47majority,butfaced a tough election cycle since they are defending twice as many seatsas Democratsthis year. Republicans did pick up a seat in Alabama, with Trump-endorsed former football coach Tommy Tuberville beating incumbent DemocraticSenator Doug Jones. The Alabama Senate seat was the only toss-up seat this year held by Democrats. .
