LAS VEGAS (AP) —
Congressional District 3
Danny Tarkanian has beaten Michael Roberson in a hotly contested Republican primary for the southern Nevada House seat held by Rep. Joe Heck.
The 3rd Congressional District race was one of the most heated in the primary cycle, with candidates trading negative ads that called each other "Dirty Danny Tarkanian" and "Two-Faced Michael Roberson."
Tarkanian is a businessman and son of the late UNLV basketball coach Danny Tarkanian.
Roberson is a lawyer who's in the middle of his second term in the state Senate.
Other Republican candidates included Assemblywoman Michele Fiore.
Tarkanian will face Democratic candidate Jacky Rosen, who defeated attorney Jesse Sbaih Tuesday.
Congressional District 4
State Sen. Ruben Kihuen has won a competitive Democratic primary race in the congressional district that includes North Las Vegas and rural central Nevada.
Kihuen topped former state Assemblywoman Lucy Flores, philanthropist Susie Lee and a handful of lesser-known candidates in the hard-fought race. Kihuen will face incumbent Rep. Cresent Hardy in November.
Hardy won the Republican congressional primary against two little-known opponents.
U.S. Senate
Former Nevada Attorney General Catherine Cortez Masto easily won the Democratic primary for Senate Minority Leader Harry Reid's U.S. Senate seat.
She'll face three-term Rep. Joe Heck, who won the Republican primary against a slate of Republican candidates including Sharron Angle, a tea party favorite who lost a competitive Senate race against Reid in 2010.
Congressional District 1
Incumbent Dina Titus won the Democratic primary in her Las Vegas U.S. House district.
