The National Rifle Association dropped $1 million on a new ad hitting Nevada Democratic Senate candidate Catherine Cortez Masto as being a repeat of retiring Sen. Harry Reid.

The ad highlights Reid’s leadership in the Senate when he was majority leader and his votes for gun control and for judges whom the ad called “anti-gun.” The ad then says Reid is trying to force Nevada to elect Cortez Masto, the Las Vegas Review-Journal reported.

“Masto doesn’t sound like Harry Reid or look like Harry Reid,” the narrator says of the former Nevada attorney general. “But she’d vote like Harry Reid.”

The 30-second ad is set to run from Tuesday to next Monday in Las Vegas and Reno.

The latest RealClearPolitics average of recent polls from the Silver State shows Cortez Masto’s opponent, Rep. Joe Heck, ahead by 4 points. The Rothenberg & Gonzales Political Report/Roll Call rates the race as a Tossup.
