A new poll from McClatchy shows GOP presidential nominee Donald Trump is the fourth choice for president among millennials. He draws only 9 percent, falling behind Libertarian candidate Gary Johnson and Green Party candidate Jill Stein. Even though Democratic nominee Hillary Clinton wins the poll, she does so with only 41 percent. She is still struggling with the younger generation.

Clinton's rival, Vermont Sen. Bernie Sanders, won more votes during the primary from millennials than the presidential nominee. Despite the media trying to claim the Democratic Party is united after the convention, many Sanders delegates and young voters have not warmed up to the idea of Clinton as the nominee.

Kristin Tate, a conservative columnist, writes in The Hill that the problems for Clinton stem from her career as a politician, her inauthenticity, her uncoolness, her unlikability and the impression that she will say anything to get elected.

"How is she supposed to motivate these young people? It's a strange position. Lacking a clear way to win through force of her personality, she must rely instead on the mistakes of her opponents," Tate wrote.

Over at Forbes, Karin Agness, the founder and president of the Network of Enlightened Women (a group before whom I have spoken multiple times), backed up Tate's assertions with interviews from convention delegates.

One delegate told her that she wouldn't vote for any presidential candidate, because although she supports many of Clinton's policies, "her words rarely match her actions and I can't trust a person whose words don't match their actions."

A recent Gallup poll found Clinton's current favorability with voters aged 18-to-29 sits at just 31 percent.

Ronald Brownstein of the Atlantic has also recently touched on Clinton's problem with millennials. He writes that registered millennial voters rival baby boomers in numbers this election cycle (30.5-30.7 percent), meaning the loss of this age group could be a disaster for Clinton.

President Obama relied heavily on this group to win the presidency in 2008 and keep it in 2012, so if millennials aren't motivated to vote for Clinton, she could struggle against Trump.

This is not to say that millennials will vote in equal numbers to baby boomers, which has so far never been the case. I'm also not saying that Clinton doing poorly with millennials means Trump is doing well — far from it. Trump is doing much worse with the younger generation than Clinton.

The problem for Clinton comes from whether enough millennials vote for her or stay home altogether. If the latter happens, the election could be closer than any non-Trump supporter could possibly imagine.
