For all the talk of how Democrats running for re-election in states President Trump won are a protective shield for Senate Republicans, Nevada's Dean Heller has the opposite problem.
He is the only Republican senator up for re-election in a state that Democrat Hillary Clinton won in 2016. The candidate challenging him for the seat is Democratic Rep. Jacky Rosen. "Right now, the Republicans have all three branches of government," Rosen said. "So what we can do is try to hold their feet to the fire every way we can, because we don't have the votes to win."
