LAS VEGAS (AP) — The Associated Press has declared Democratic Rep. Dina Titus the winner in her race for reelection to the U.S. House. It was the second election in a row that Titus defeated Republican Mark Robertson to keep her seat in the Las Vegas district she has represented for more than a decade. The races for the seats sought by Reps. Susie Lee and Steven Horsford were too early to call. Nevada’s lone Republican Congressman, Mark Amodei, cruised to victory Tuesday night.
