While the Rosen entry gives the Democrats a credible challenger, her first experience as a political office seeker drew mixed reviews. Winning a marginal Las Vegas area district, even one where President Trump scored a 48-47% victory over Hillary Clinton, the new Congresswoman’s 47-46% victory margin opposite perennial Republican candidate Danny Tarkanian was not particularly inspiring. The $1.7 million she spent is about average for a targeted open seat, but under what was expected for a major toss-up campaign. Her 3rd District was vacated in the 2016 election because Republican incumbent Joe Heck (R-Henderson) ran unsuccessfully for the Senate.
The development sets the stage not only for a top tier Senate campaign, but also a highly competitive open 3rd Congressional District, a seat the Democrats will risk losing.
