Hillary Clinton won the Nevada caucuses Saturday thanks to support from women, African-Americans and older voters, according to entrance polls that surveyed voters as they arrived at caucus sites across the state.

Here are 5 key findings from the entrance poll:

The gender gap was alive and well in Nevada on Saturday, with Clinton carrying women by a 16-point margin, 57 percent to 41 percent.

That helped offset a 9-point edge for Sanders among male voters, 53 percent to 44 percent.

Women made up 56 percent of caucus-goers, according to the entrance poll.

Clinton ran up huge margins among African-American voters, 76 percent to 22 percent. They comprised about one-in-10 of her supporters and provided much of her margin of victory on Saturday.

For all the parallels to 2008, Clinton’s dominance among black voters is a huge turnaround from 2008 – and a reflection of the changed dynamic in her campaign against Sanders, a 74-year-old Brooklyn-raised Vermont senator, as opposed to Barack Obama eight years ago. Clinton won only 14 percent of the black vote in 2008.

The entrance polls show Sanders edging Clinton among Hispanics, who made up roughly one-in-five voters on Saturday, 53 percent to 45 percent.

Entrance polls are just that – polls – and the sample of Hispanic caucus-goers here fewer than 200 people. That means the margins of error for both candidates’ vote shares are plus or minus 7 percentage points.

Some commentators suggest Clinton’s advantage in Clark County – she had a roughly 10-point lead in the state’s most populous county – calls into question the veracity of the entrance poll finding for Hispanic voters. But even if Sanders didn’t actually win Latinos by 8 points as the entrance poll states, his strong performance suggests he made significant inroads in a community previously thought to be part of the Clinton firewall.

As in Iowa and New Hampshire, older voters favored Clinton. But she increased her margin among seniors in Nevada, according to the entrance poll, blowing out Sanders, 74 percent to 24 percent.

Clinton won just 54 percent among seniors in New Hampshire, and 69 percent in Iowa.

But younger voters continue to favor Sanders by overwhelming margins: Sanders won caucus-goers under 30, 83 percent to 16 percent.

When the race moves to the dozen and a half states (plus the District of Columbia) with closed primaries, Clinton’s advantage among Democrats – and Sanders’ reliance on independents – portends well for the former secretary of state.

Among the four-in-five caucus-goers who identified as Democrats, Clinton won them, 58 percent to 40 percent. But among independents, Sanders carried them easily, 71 percent to 23 percent.

Voters in South Carolina next Saturday aren’t required to be registered Democrats – but they must sign an oath that they didn’t vote in the Republican primary.

The entrance poll was conducted by Edison Research on behalf of a consortium of news organizations (ABC News, CBS News, CNN, Fox News, NBC News and The Associated Press) and surveyed 1,024 voters as they arrived at caucus sites.
