While the passionate youth movement for Bernie Sanders has captured the spotlight, some millennials -- voters between 18 and 35 -- are taking a serious look at Donald Trump.

A Harvard Institute of Politics poll this spring found that 25 percent of people under 30 said they'd vote for Republican Donald Trump if he faced off against Democratic front-runner Hillary Clinton in the general election this fall.

Sanders, an independent turned Democrat, still has the clear advantage among millennials. The same poll found that 80 percent of those who hold a favorable opinion of Sanders would vote for Clinton if he drops out of the race.

According to The Associated Press, both Sanders and Trump have been successful in tapping into the anger and disillusionment of the millennial generation. Millennials tend to be suspicious of all things establishment-related, whether it is the voting system or corporate influence over the economy. The Sanders and Trump campaigns highlight what is broken with the government and focus on how they will fix it.

Because Clinton is more closely tied to the establishment, her popularity with millennials has suffered, according to the Harvard poll.
