Conservatives who are skeptical of school choice — what's your reasoning?

School choice has been a priority of many conservatives in recent years, with a more than a dozen conservative-leaning states enacting or expanding voucher/ESA programs. But in 2024, voters in Kentucky and Nebraska rejected school choice ballot measures by meaningly margins.

That suggests a meaningful number of conservative voters aren't on board. If you're one of them, or if you understand the hesitation, what drives it? Is it about concerns about accountability, a belief that government should fund public education specifically, or something else?
