One of the worst things about Obamacare is that it provides taxpayer funding of abortion. This is one of the nearly countless reasons why Obamacare must be repealed, and it’s one of the core reasons why it is crucial for Republican presidential candidates to show they have an alternative that would lead to repeal. So far, only Scott Walker has stepped up in this regard.  For pro-life voters, this should matter greatly.

(Bobby Jindal, a second-division presidential candidate, has also released an Obamacare alternative, but it is so full of political holes—no answer for the poor or near-poor, disruptive to the employer-based market—that it would arguably be less likely to lead to repeal than no alternative at all.)
