Democratic candidates debate in Detroit Michigan, July 30-31, 2019: on Education

Julian Castro: Inner cities need help; invest in education

I would invest in housing that is affordable, because folks know that the rent is going through the roof. And we need to make sure that you don't have to get out of West Baltimore, or Inner City Detroit, or the west side of San Antonio, or anywhere, if you want to reach your American dream. I want you to be able to accomplish it in your great neighborhood where you are.

Kamala Harris: FactCheck: Did not desegregate LA and SF school districts

The context: Yes, both districts have struggled to better integrate. But it was difficult -- and highly unusual -- for a state attorney general at that time to file suit to desegregate a school, said [a California schools expert].

A series of federal court decisions in the mid-1990s made it much tougher to bring desegregation lawsuits. Few state attorneys general even try. "There was nothing she could really do in San Francisco to force the district to use race-conscious efforts to desegregate the schools. The legal standard would be very difficult to prove," the expert said. "San Francisco has tried a lot of different things to make less segregated schools -- it's just a very difficult thing to do."

Amy Klobuchar: Let graduates refinance loans at a better rate

Beto O`Rourke: Free 2-year college, and debt-free 4-year college

O'ROURKE: I support free two-year college, earn that associate's degree, realize your full potential, debt-free four-year college. But that's not just for tuition. That is room and books and board, the full cost of being able to better yourself so that you can better this country. For that schoolteacher who is working a second or a third job, full forgiveness for her outstanding student loan debt, forgiveness for that person willing to work at the V.A. and serve our former service members. And we do not do that at the expense of unions. We make it easier to join an apprenticeship to learn a skill or a trade that you can command for the rest of your life.

Elizabeth Warren: Universal tuition-free college plus more for HBCUs

Marianne Williamson: Getting rid of college debt will stimulate economy

Pete Buttigieg: Public-service loan forgiveness program

BUTTIGIEG: That would be great for us. The next day, people would be out taking student loans wondering why they weren't lucky enough to get theirs wiped away completely, too. We can have debt-free college for low and middle-income students by expanding Pell Grants and compelling states to pick up more of the burden. For those who have a lot of debt, we can expand a public service loan forgiveness program, which is an excellent program that is almost impossible to actually get access to right now.
