Democratic National Committee chair Tom Perez told CNN's Chris Cuomo Monday he could expect a "surprise" in the Senate, but it didn't materialize as Republicans expanded their majority.
"I think we're going to surprise a lot of people in the Senate," he said. "Is the pathway narrower in the Senate? Absolutely. But we've got four viable opportunities to play offense."
While Perez correctly predicted Democrats would recapture the House majority, Republicans picked up Senate seats in Indiana, North Dakota and Missouri, and they appear likely to also score a pick-up in Florida with Rick Scott leading Sen. Bill Nelson (D.) there.
Republicans also played good defense, holding off tough Democratic challengers in Texas against Beto O'Rourke and Tennessee against Phil Bredesen. Martha McSally leads her challenger Kyrsten Sinema in Arizona, where they are vying for the seat being vacated by Sen. Jeff Flake (R., Ariz.).
The only Democratic pick-up of the night came in Nevada with the ousting of Sen. Dean Heller (R., Nev.). Nevada was the only state in the country Hillary Clinton won in 2016 where an incumbent Senate Republican was seeking re-election.
