Talk surrounding the latest USA Today/Rock the Vote poll is centered on Donald Trump's historic loss with young voters, but these results don't mean Hillary Clinton has secured the youth support she needs. After enjoying a post-convention boost, the poll has her at 50 percent compared to Trump's 18 percent. Libertarian candidate Gary Johnson has 11 percent, while 10 percent wouldn't vote and 8 percent don't know. In a race between the two of them, Hillary leads Trump with 56-20 percent.

The numbers match up almost exactly with the ideological leanings of the poll's respondents. Half of the respondents, which are voters under 35, identify with or lean toward the Democrats. Twenty percent identify with or lean toward the Republicans, while 17 percent are independents and 12 percent identify with a third party or don't know.

In addition to her 36-point lead, which becomes a 32-point lead when Johnson is included in the race, Hillary enjoys 72 percent of support from Bernie Sanders supporters. However, the poll acknowledges "she has failed so far to generate the levels of enthusiasm Sanders did — and the high turn-out that can signal — among millennials." The poll also provided Sanders supporters with a limited amount of options, including voting for Donald Trump (11 percent), won't vote (11 percent), and don't know (8 percent). Previous polls have provided the option of a third-party candidate, which former Sanders supporters have overwhelmingly chosen.

In the January poll, Hillary had a slight overall edge over Sanders with Democratic and independent millennials at 46-35, but that edge vanished when it came to younger millennials and young women, whom Sanders held an almost 20-point lead over.

Hillary's 50 percent of support from millennials is higher than other polls, though still not at the level Barack Obama enjoyed in 2008 and 2012. As other polls have shown, even those who say they will vote for her are not enthused, and she recently hit her lowest favorable marks with young people according to a July Gallup poll.

These results are hardly good news for Donald Trump. The poll noted his "weakness among younger voters is unprecedented, lower even than the 32 percent of the vote that the Gallup Organization calculates Richard Nixon received among 18-to-29-year-old voters in 1972, an era of youthful protests against the Vietnam War."

Millennials comprise the largest voting bloc at over 75 million, but also have the lowest voter turnout. If enough stay home, which polls indicate is a possibility, Trump could win the election.

The online poll was conducted by Ipsos Public Affairs from Aug. 5-10 and surveyed 1,539 adults age 18-34. It has a credibility interval, akin to the margin of error, of 4.6.
