School choice is a winning policy, so why don't Democrats support it?

What if I told you that a policy proposal has a 73 percent approval rating? That includes 76 percent of Hispanics, 73 percent of whites, and 69 percent of African Americans. And 56 percent of those polled said they would be more likely to vote for a candidate who supported this policy. If you were a Democratic candidate for president, you would naturally think that supporting such a policy would be a smart thing to do.

What is this popular public policy?

Is it "Medicare-for-all"? Is it the "Green New Deal"?

No. It’s school choice.

In a June nationwide poll from Mason-Dixon Polling on behalf of the American Federation for Children, 73 percent of voters said they support school choice programs that give "parents the right to use the tax dollars designated for their child’s education to send their child to the public or private school which best serves their needs."
