It’s a start.

MIDDLETON — Wisconsin Gov. Scott Walker says he doesn’t have a number in mind for how much he wants to grow the private-school voucher program, should he be elected to a second term.

Walker said Wednesday after touring a sensor manufacturer in Middleton that he wants to grow the program in stages, so there is capacity for all the students who wish to participate.

Walker has been an advocate for school choice for years, so we know his heart is in the right place. Personally, I’d like to see something more bold. Let’s do full, statewide school choice that’s available to any family who chooses to participate. It is difficult to make any rational argument as to why the government should only allow an arbitrary few families a choice in a handful of districts while families elsewhere do not get that choice. Why is a kid struggling in the Hudson district, for example, any less deserving than one in Milwaukee?

Tear down this cap, Governor Walker!
