Democratic gubernatorial candidate Steve Sisolak is launching a new television ad highlighting his goals of reducing class sizes and raising teacher pay.

Sisolak’s ad, called “Too Many,” starts Thursday in Las Vegas and Reno television markets as part of a six-figure buy, and is the Clark County Commission chairman’s fifth ad of the primary season.

“Too many schools have too many crowded classrooms. Too many teachers earn too little to live on. Too many times, Nevada ranks too low in education,” Sisolak says in the ad, which features imagery from schools. “And for too long, too many politicians have done too little about it. That’s about to change.”

Earlier this year, Sisolak said he wants to find a way to adjust property tax caps to bring in more revenue for education. Such an effort failed in the 2017 legislative session amid Republican concerns about raising taxes.

His ad goes on to vow not to take a salary until schools improve. Fellow Democratic candidate and Clark County Commissioner Chris Giunchigliani’s campaign criticized the salary move when it was first announced by panning Sisolak’s support of $750 million in public funding for the Raiders’ future Las Vegas stadium.

“If we didn’t give away three quarters of a billion dollars for the stadium and instead funded our schools, we wouldn’t see silly stunts like this,” her campaign manager, Eric Hyers, said in February.

It comes a week after the Nevada State Education Association (NSEA) teachers union announced it was spending $1 million on ads boosting his primary opponent.

A Nevada Independent poll taken in mid-April shows Sisolak is significantly ahead of Giunchigliani in the Democratic primary, but many voters remain undecided. Sisolak has gained the endorsement of the Clark County Education Association, which is in a bitter schism with NSEA.
