LAS VEGAS (AP) — The Associated Press has declared Democratic Reps. Dina Titus and Steven Horsford the winners in their races 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. Horsford beat former North Las Vegas Mayor John Lee. The race for Rep. Susie Lee’s seat remained too early to call. Nevada’s lone Republican Congressman, Mark Amodei, cruised to victory Tuesday night.
