Vermont Senator Bernie Sanders has opened up a commanding 19-point lead over party front-runner Hillary Clinton among female millennials in their tightening race for the 2016 Democratic presidential nomination.

Real Progressive Politics reports a recent USA Today/Rock the Vote poll now finds Sanders bagging 50 percent of the vote among that demographic to Clinton's 31 percent.

Women millennials are described as voters falling between the age range of 18 to 34 -- a group the 74-year-old Sanders is heavily counted on in hopes of putting him over the top against the former Secretary of State and First Lady in the critical, early-voting states of Iowa and New Hampshire.

"The challenge of this election is to disprove the skeptics who believe (young people) don't vote," Sanders' senior adviser Tad Devine told USA Today. "Obama and his campaign took that on, they disproved it, it became the source of their victory. We're trying to do the same thing."

Eight years ago, a still relatively unknown Barack Obama emerged to win the Iowa caucuses fueled by a voter turnout that nearly doubled figures from just four years earlier. His greatest support came from 17- to 44-year-olds, while Clinton won among those 65 and older, placing her third in the state overall.

Current polling shows Sanders now garners 57 percent support from 18-25 year olds and 36 percent from among 26-34 year olds. Meanwhile, Clinton gets 44 and 25 percent support from those two groups, respectively.

Sanders has worked tirelessly to keep that base of his supporters energized and many among it insist they find him more trustworthy than other candidates.Data also shows millennial women seem less inspired than some older voters by the prospect of electing the first female president.

"Even though having a woman in the White House would be new and different, it's hard to feel like Hillary Clinton is new and different," said Krystal Ball, contributor to Glamour magazine's 2016 election project "The 51 million."

She later added, "They're expressing their disgust and frustration with a political system," and Sanders is proving the beneficiary of much of the anger.

It's all helped create an atmosphere where the stakes will be exceedingly high when the two face off in Sunday night's fourth democratic debate. Iowa and New Hampshire are considered Sanders' best shots at early voting success and his last best chance to thwart what could be an overwhelming momentum for Clinton.

Currently, Sanders is rumored to be leading Clinton in New Hampshire, where four of the last five polls taken in the state have put him ahead, and running neck and neck with her in Iowa. According to Fox News, a Bloomberg/Des Moines Register poll now has Clinton leading Sanders 42 to 40 percent.
