Trump expected to sign executive order prioritizing federal funding for school choice programs

It's less that and more public schools are already under funded, and this will just make them even more under funded, possibly leading to closures and consolidation of public schools. All of this will make public schools worse and private (mostly religious/Christian) look like a better and better option for your children.

Public schools are funded by an amount set by the government, but private schools are funded by what the school demands. This allows private schools to be better funded because they'll demand that the money per student is higher, and when it's the tax payer that is paying it, more and more parents won't notice or care about price anymore (since it isn't coming from their pocket) and will pick the better funded school and hope to deal with the consequences (of indoctrination) later (if they know about it at all until too late).

This is something that the Republicans would like since religious schools typically tell students that Republicans (aka God fearing people) are good and Democratic (aka not God fearing) are bad and real Christians always vote for the Republican party. Indoctrination from the start. And the Republicans get to wash their hands of any negative claims because "it's not a government school" so free speech and all that. Don't like it? Go to the worse and horribly under funded public schools instead.

It depends, is your priority education or public education? That's what the debate is about
