About the 2016 Senate elections

Trump's win over Hillary Clinton surprised most forecasters, and so did the Senate results. Democrats had hoped to win the chamber, but Republicans held almost every competitive seat. Democrats won 12 Senate races and Republicans 22. Democrats gained only Illinois, where Tammy Duckworth beat Mark Kirk, and New Hampshire, where Maggie Hassan beat Kelly Ayotte by about 0.1 points. Republicans kept a 52-48 majority. In Pennsylvania, Pat Toomey beat Katie McGinty by 1.4 points, and in Wisconsin Ron Johnson beat Russ Feingold again, this time by 3.4 points. Roy Blunt held Missouri against Jason Kander, and Richard Burr held North Carolina. Marco Rubio, who had said he would not run again after his presidential campaign, changed his mind and won Florida. John McCain won a sixth term in Arizona. In Nevada, Catherine Cortez Masto held Harry Reid's seat for the Democrats and became the first Latina senator. In Indiana, Evan Bayh's comeback attempt failed against Todd Young.
