Hillary Clinton enters Wednesday’s debate in Las Vegas with a 7-point lead over Donald Trump in Nevada, according to a new poll released Tuesday.

The Monmouth University poll shows Clinton leading Trump, 47 percent to 40 percent, with 7 percent of likely voters backing Libertarian Gary Johnson. Two percent indicate they will choose the “none of these candidates” option on the Nevada ballot, while 1 percent support another candidate and 3 percent are undecided.

In the previous poll, conducted last month prior to the first Clinton-Trump debate, the Republican had a 2-point lead over Clinton, 44 percent to 42 percent.

The Monmouth poll gives Clinton a larger lead than a CNN/ORC International poll released on Monday. Clinton’s advantage in that poll was only 2 points, 46 percent to 44 percent. The CNN poll was conducted last Monday through Saturday, while the Monmouth poll is more recent: last Friday through this Monday.

Clinton’s surge in Nevada comes from improved standing with non-white and younger voters. Clinton now leads by 49 points among non-white voters, 67 percent to 18 percent, up from a 35-point lead last month. And she now leads by 27 points among voters under age 50, 55 percent to 28 percent, up from only a 1-point advantage last month.

The poll surveyed 413 likely voters and has a margin of error of plus or minus 4.8 percentage points.

But Clinton’s increasing support isn’t boosting Democratic Senate candidate Catherine Cortez Masto, however. The poll shows GOP Rep. Joe Heck leading Cortez Masto, 45 percent to 42 percent — virtually unchanged from Heck’s 3-point lead over Cortez Masto, a former state attorney general, last month.

That’s despite other polls, including the CNN/ORC survey on Monday, that show Cortez Masto emerging with the advantage over Heck. Cortez Masto led by 7 points in the CNN/ORC poll, and by 5 points in a survey conducted for KLAS-TV, the CBS affiliate in Las Vegas. A SurveyMonkey poll conducted over the internet for The Washington Post over the past week-and-a-half shows Heck and Cortez Masto running neck-and-neck.

Some Republicans suggested Heck could lose support among Republicans for abandoning Trump after the tape of Trump boasting of groping women emerged earlier this month. But according to crosstabs provided to POLITICO, Heck is actually winning a higher percentage of Trump voters in the poll (86 percent) than Cortez Masto is winning Clinton voters (78 percent).

Two prominent Clinton surrogates will be campaign for both Democratic candidates in the coming week: Sen. Bernie Sanders (I-Vt.) will be in Reno on Wednesday, and President Barack Obama will campaign in Las Vegas on Sunday, one day after early voting begins in the state.
