Broadly speaking, Sanders and Warren have similar (but by no means identical) plans: Both proposed free public college and community college, along with more Pell Grants, to help students pay for other college-related expenses. In addition, they both want to cancel massive amounts of student debt — all of it in Sanders’ case, and much of it in Warren’s case.

Meanwhile, former Vice President Joe Biden and Minnesota Sen. Amy Klobuchar have (again, somewhat similar but not identical) more moderate plans. They both propose tuition-free community college. In addition, they both want to beef up Pell Grants and strengthen or expand programs to help people repay their student loan debt.

Buttigieg’s plan stakes out a middle position between those two wings. It would make public college free for all students from families earning up to $100,000 annually. It would also offer assistance for families earning more than that, phasing out at $150,000. In addition, he would take steps to help people deal with debt, like automatically enrolling debtors in income-based repayment programs and expanding public service loan forgiveness programs.
