Hillary Clinton may be leading her competitors with the millennial demographic, but the results of a recent Gallup poll show she doesn't have much to celebrate. The poll addresses "Hillary Clinton's Continuing Youth Problem," showing that the problem is not only continuing, it's reached its worst point. Only 31 percent of millennials have a favorable opinion of Hillary.

The low favorable ratings are worse considering a year ago 47 percent of those 18- to 29-year-olds had a favorable opinion of her.

Hillary is barely viewed positively even among young Democrats. She holds a favorable rating of 48 percent to 47 percent unfavorable. That number is much higher for Democrats in all other age groups. The Washington Examiner spoke with young Democrats at the DNC, where only one-in-four said they wanted to vote for her. At a Harvard IOP youth town hall, most were not enthusiastic about Hillary.

Young Americans began to view Hillary more unfavorably in February and March, and her numbers have been dropping ever since.

"Clinton's image has dropped among all age groups but has fallen the most with young Americans," according to Gallup.

At this point, Hillary would do far worse than Barack Obama, who won re-election with 67 percent of the youth vote, which allowed him to win the swing states of Ohio, Florida, and Virginia. Others have warned that young swing states voters who stay home could jeopardize Hillary's chances.

"This could create real problems for her campaign if it does not change in the weeks ahead," Gallup said. "Young Americans should be Clinton's natural constituency. Half identify or lean Democratic, and 31 percent identify as liberal, the ideology most often associated with the Democratic Party."

The Democratic nominee is unpopular with other age groups as well. Forty percent of 30-49 year olds view her favorably, as do 41 percent of 50-64 year olds, and 39 percent of those older than 65. Hillary is struggling with these older voters who actually supported her in the primary.

The poll results are similar to last month's McClatchy-Marist poll.
