Roe v. Wade

ROE v. WADE....I don't want to spend a ton of time rehashing last night's debate, but what did John McCain mean in this exchange about Supreme Court nominees?

Schieffer: But even if it was someone — even someone who had a history of being for abortion rights, you would consider them?

McCain: I would consider anyone in their qualifications. I do not believe that someone who has supported Roe v. Wade that would be part of those qualifications. But I certainly would not impose any litmus test.

First, he'd consider anyone "in their qualifications." Then he says that support for Roe v. Wade would be a qualification that would cause him to reject a candidate. But then he says there's no litmus test.

What did that mean? Just random incoherence? Or is there some subtlety I'm missing?
