Voting is underway in the Nevada caucuses. While we are still waiting for official results, we have some numbers from early entrance polls — and they look good for Sen. Bernie Sanders (I-VT).

First, the usual disclaimer about entrance polls: They don’t always capture the results accurately and have been wrong before. In the past, some entrance polls have discounted Latino voters, appearing to skew the results for a different candidate before the actual votes came in.

Numbers from entrance polls are still rolling in as pollsters continue to interview voters. That said, the early data from major TV networks and newspapers is showing Sen. Bernie Sanders in the lead.

NBC poll of early voters: Sanders ahead with early voters

NBC has a poll of Nevadans who voted during the state’s early voting period, based on interviews of 2,122 voters’ initial preferences. Per NBC’s Steve Kornacki, Sanders is strong in multiple categories; the NBC poll shows Sanders leading among white voters (which make up about 66 percent of Nevada voters) and with a wider lead among Hispanic voters (about 17 percent of Nevada voters). Meanwhile, former Vice President Joe Biden leads among African American voters (about 10 percent of Nevada voters).

Here’s the NBC breakdown among demographics:

Sanders — 31 percent

Former South Bend, Indiana, Mayor Pete Buttigieg — 18 percent

The CNN entrance poll also found three in five Nevada caucus-goers decided whom they’d be voting for before February, compared to two in five voters who reported deciding in the past month.

Early polling also seems to suggest Nevada voters agree with Sanders on Medicare-for-all: CNN’s entrance poll showed 62 percent of Nevadans support the policy.
