A solid majority of Americans - 57% - who've already paid off their student-loan debt support Sen. Elizabeth Warren's ambitious new plan to cancel tens of millions of Americans' student debt, according to a new INSIDER poll.

The Massachusetts Democrat's proposal would forgive $50,000 in student loan debt for every American whose family makes up to $100,000, and households that make between $100,000 and $250,000 would get a sliding portion of their debt cancelled. In addition, Warren's plan would make all public higher education, including community colleges, tuition- and fee-free.

INSIDER's poll found that 82% of Americans who are currently paying off student loans support Warren's plan to forgive their debt. Notably, a majority of respondents - 54% - who didn't take out any student loans to pay for higher education support the plan, as do 53% of those who didn't attend college or graduate school.

Overall, 57% of Americans at least somewhat support the 2020 candidate's debt cancellation proposal and 21% opposed the measure. 13% of respondents did not either support or oppose the idea while 9% said they didn't know how they felt about the plan.

Warren's plan is vast in scope: it would eliminate all student debt for 75% of Americans who have it, and get rid of at least some debt for 95% of the almost 45 million affected Americans, according to an analysis by four social policy professors released by Warren's campaign.

The poll also found deep support among Democratic primary voters. 77% of Democrats who said they'd likely vote in the 2020 presidential primary were either somewhat or strongly supportive of the proposal's debt cancellation.
