The National Republican Senatorial Committee is expressing support for Sen. Dean Heller, who now faces a primary challenge from Danny Tarkanian. In a statement shortly after Tarkanian announced his candidacy, committee spokesman Michael McAdams says Heller has repeatedly “proven he is unafraid to put Nevadans first.” Tarkanian has attached himself to Donald Trump and criticized Heller’s votes on health care. Tarkanian says “Heller turned his back on us.” Heller campaign labels Tarkanian a perennial candidate who voters have rejected everytime.
