Hillary Clinton pulled out a crucial victory in Nevada's Democratic presidential caucuses Saturday, overcoming an unexpectedly strong surge by Bernie Sanders and easing the rising anxiety of some of her supporters.

"Some may have doubted us, but we never doubted each other," Clinton told her cheering supporters during a victory rally in Las Vegas. "This one is for you."

Clinton captured the backing of voters who said electability and experience were important in their vote. But in a continuing sign of her vulnerability, Sanders did best with voters looking for a candidate who is caring and honest.

Sanders said in a statement that he'd congratulated Clinton on her victory, but then declared his campaign has "the wind at our backs as we head toward Super Tuesday" - the multi-state voting contests on March 1.

Clinton's victory in Nevada could be vital in holding off a challenge from Sanders that has been tougher than almost anyone expected. Clinton and Sanders split the first two voting contests, revealing the Vermont senator's appeal with young people drawn to his impassioned calls for breaking up Wall Street banks and providing free tuition at public colleges and universities.

According to the entrance polls of voters, Clinton was backed by a majority of women, college-educated voters, those with annual incomes over $100,000, moderates, voters aged 45 and older and non-white voters. Sanders did best with men, voters under 45 and those less affluent and educated.

Clinton's win means she will pick up at least 18 of Nevada's 35 delegates. She already holds a sizeable lead in the delegate count based largely on her support from superdelegates - the party leaders who can support the candidate of their choice, no matter the outcome of primaries and caucuses.
