Sen. John McCain helped catapult former Alaska Gov. Sarah Palin to the national stage and now he's equating her to former President Ronald Reagan. He made the comparison Sunday when asked if Palin is "divisive." "I think anybody that has the visibility that Sarah has is obviously going to have some divisiveness," McCain said on CNN's "State of the Union." "I remember that a guy named Ronald Reagan used to be viewed by some as divisive." The former Republican presidential nominee called Palin "an incredible force in the American political arena" and said she's "keeping her options open."
