A new public opinion survey in the crucial western swing state of Nevada points to a surge in support by Republican Senate nominee Adam Laxalt with just under four weeks to go until Election Day.

According to a Suffolk University poll for USA TODAY that was released on Wednesday, the former state attorney general trails Democratic Sen. Catherine Cortez Masto by just two points 46%-44% among likely voters in Nevada. That’s down from a seven-point lead for the Democratic incumbent in the previous USA TODAY/Suffolk University poll in the Silver State, which was conducted in August. 

Laxalt has gained ground after his campaign and allied Republican groups have blasted Cortez Masto over the economy and inflation, and thanks in part to an increase in support among Hispanic voters.

According to the poll, the negative ads against Cortez Masto have driven up her unfavorable ratings, and her lead among Hispanics has shrunk from 18 points in August to seven points now.

Suffolk University Political Research Center director David Paleologos noted that Laxalt’s economic message may be resonating with Latino voters, as he pointed out that" 48% of Hispanics named the economy/inflation as the number one issue, higher than whites (43%) and Blacks (23%)."

THESE 11 SENATE RACES WILL DETERMINE THE CHAMBER'S MAJORITY

The Iraq War veteran and grandson of the late Nevada governor and senator Paul Laxalt, and Cortez Masto, a former two-term state attorney general who made history in 2016 as the first Latina elected to the Senate, are facing off in a race that’s among a handful across the country that will likely determine if the GOP wins back the chamber’s majority in November’s midterm elections.
