A new Bankrate Money Pulse survey finds that a majority of Americans support making college tuition free, but the survey also suggests that they don't know how it will work.

Sixty-two percent of all Americans are in favor, which includes 77 percent of millennials.

Morley Winograd, president and CEO of the Campaign for Free College Tuition, said that because millennials are the generation most impacted by skyrocketing tuition prices, they "see free college tuition as an important part of the changes in American society they plan to make."

Joe Orsolini, a CFP professional with College Aid Planners, said that those in favor likely haven't thought the idea through.

"I don't think the product will be the same as it is today," he said. "A lot of choices and options that people are used to in the current system will go out the window."

Forty-eight percent are unwilling to pay more in federal taxes for free college, suggesting that they indeed have not thought it through. Where do Americans think "free" college is coming from? They can't really expect it to be free? A Rasmussen poll from July found that most Americans see through the ruse.

The Bankrate survey also found divides along political lines. While 81 percent of Democrats and 67 percent of independents support the concept, only 33 percent of Republicans do.

About a quarter of those who oppose free tuition changed their minds for families making less than $50,000. Hillary's plan will allow students whose families make under $125,000 a year to attend a public institution by 2021.

While the poll shows that Americans are in favor of free tuition, so long as they don't have to pay more taxes for it, they're not so keen on debt forgiveness. A plurality, at 40 percent, say those with student debt should be required to make payments until the debt is paid. A third of millennials agree. Thirty-five percent of Americans say they support debt forgiveness after 10 years.

As experts have warned, college tuition rises along with government involvement, and offering "free" college tuition could end up making it even more costly. Still present are the concerns of other costs not associated with tuition, that still lead to debt, especially for those who take more time to graduate or never do so.

In addition to free tuition for for most families, Hillary's plan involves loan forgiveness.
