This week, another GOP contender for president released a plan for replacing Obamacare — demonstrating again that yes, there are Republican alternatives.

As with the plan proposed earlier this year by Florida Senator Marco Rubio, the main feature of Wisconsin Gov. Scott Walker’s plan to change the pre-Obamacare status quo is a refundable tax credit for those who buy insurance outside their workplace. This is designed not only to ease the transition away from an Obamacare system laden with mandates and subsidies that drive up the cost of care, but also to make insurance affordable for more people than it was before Obamacare.
