Although he’s already on shaky ground with conservative Republicans, John McCain told the Weekly Standard yesterday that he won’t rule out the possibility of choosing a pro-choice running mate:

“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.”

Even though the pro-life stance is a fundamental tenet of the Republican Party, McCain said “that does not mean we exclude people from our party that are pro-choice.”
