It has been clear for some time that Republicans need just two things in order to repeal Obamacare—a winning alternative and political willpower. The jury is still out on how much of the latter the party possesses. But when it comes to uniting around a well-conceived alternative that can pave the way to full repeal, the news is increasingly good. Jeb Bush’s just-released Obamacare alternative is the latest example of this encouraging trend.

Bush’s alternative would fix what the federal government had already broken even before Obamacare was passed and made everything so much worse.  For 70 years, Americans have gotten a tax break for getting health insurance through their employer, while millions of their fellow citizens who have bought insurance on their own have gotten no tax break whatsoever.  Bush’s plan would end this inequality in the tax code, which is at the root of America’s (pre-Obamacare) health-insurance woes.
