McCain flying Ridge trial balloon?

From the Weekly Standard:

John McCain said that he is open to choosing a pro-choice running mate and named former Pennsylvania governor Tom Ridge as someone who merits serious consideration despite his support for abortion rights.

[...]

"I think that the pro-life position is one of the important aspects or fundamentals of the Republican Party," McCain said. "And I also feel that--and I'm not trying to equivocate here--that Americans want us to work together. You know, Tom Ridge is one of the great leaders and he happens to be pro-choice. And I don't think that that would necessarily rule Tom Ridge out."

[...]

"I think it's a fundamental tenet of our party to be pro-life but that does not mean we exclude people from our party that are pro-choice. We just have a--albeit strong--but just it's a disagreement. And I think Ridge is a great example of that."
