Millennials like choice: We have dozens of food delivery, dating, and exercise apps. Why should we be stuck with only two presidential candidates?

That's the way many millennials feel, especially those who would vote for Hillary Clinton if you put a gun to their head. However, 25 percent of Gen Y voters would abandon the Democratic nominee for a third-party option, according to a Quinnipiac poll released on Thursday.

In a head-to-head matchup, Clinton trounced Donald Trump with millennial voters 64 to 29 percent, respectively.

But Clinton's support drops 25 percent among millennials when the Libertarian Party's Gary Johnson and the Green Party's Jill Stein are added as viable candidates.

In a four-way race, Clinton leads with 48 percent, Trump follows with 24 percent, Johnson has 16 percent, and Stein has 11 percent.

According to the poll, millennials are the first age group with a majority of voters willing to consider a third-party candidate. Sixty percent say they'd be willing to vote for a different option than Republican or Democrat.

That shift is mostly due to the fact that millennials don't have the same feelings towards Clinton that they did for Obama in 2008 or 2012. A whopping 49 percent have an unfavorable opinion of the Democratic nominee, and another 8 percent say they don't know enough about her.

Hillary doesn't have a lock on the White House unless millennials voters decide to change their minds. As of right now, most of them aren't with her.
