Republican National Convention delegate and pro-life activist Kristy Burton is a John McCain supporter.

But with talk of McCain gauging reaction to a potential pro-choice running mate, Burton told PolitickerCO.com that she wouldn't support McCain's vice-presidential pick until he or she is pro-life.

"I certainly hope he does not pick a pro-choice running mate," said Burton, the leading proponent of Amendment 48, which would amend the state constitution to define a fertilized human egg as a person.

"(McCain) said life begins at conception, and he's been pro-life for a long time, so I'd be a bit surprised if he picks a pro-choice vice-president," Burton said. "I don't think that'd be a good choice on his part."

Burton said she wouldn't support former Department of Homeland Security Secretary Tom Ridge because of his pro-choice views. Asked about former Massachusetts Gov. Mitt Romney, Burton paused.

"To be honest, I haven't followed the presidential race to a huge degree just because of my own (Personhood Amendment) campaign that I'm involved in," Burton said. "So I'll probably just wait to see who he picks and then I'll decide what I'll do."
