Sen. John McCain said Sunday he would not necessarily support his former running mate if she chose to run for president. Speaking to ABC's "This Week," McCain was asked whether Alaska Gov. Sarah Palin could count on his support. "I can't say something like that. We've got some great other young governors. I think you're going to see the governors assume a greater leadership role in our Republican Party," he said. He then mentioned governors Tim Pawlenty of Minnesota and Jon Huntsman of Utah.
