As the only Republican senator up for re-election in a state where Hillary Clinton won in 2016, Nevada Sen. Dean Heller is the most endangered member of his party. First-term Rep. Jacky Rosen (D) is challenging Heller. Nevada has two competitive races for open House seats. In the Las Vegas suburbs, Democrat Susie Lee is taking on perennial candidate Danny Tarkanian (R), the son of hall of fame UNLV basketball coach Jerry Tarkanian, to replace Rosen. In the 4th District, two former members of Congress, Steven Horsford (D) and Cresent Hardy (R), are trying to replace Rep. Ruben Kihuen (D), who isn't seeking a second term due to sexual harassment allegations. Nevada's gubernatorial race is also expected to be competitive: Republican Attorney General Adam Laxalt faces Democrat Steve Sisolak, the chairman of the Clark County Commission.
