Republicans have secured the Senate majority after a series of GOP upsets in key states across the U.S., including in red states such as Indiana and North Dakota.
Between the lines: There are 10 Senate Democrats running for re-election in states that President Trump won. Their challenges explain why Republicans are already projected to keep control of the Senate.
