The first major victory of the modern school choice movement came from a bipartisan effort, when Wisconsin Democratic state Rep. Annette Polly Williams introduced legislation in 1990 to create the Milwaukee Parental Choice voucher program. Her bill was eventually signed into law by Republican Gov. Tommy Thompson and found support among civil rights leaders, as well as conservative and libertarian groups.

Unfortunately, three decades later, legislative support for school choice is much less bipartisan — even though it’s more popular among voters today than it’s ever been.
