(CNN) - Mike Huckabee has largely avoided criticizing Republican rival John McCain this primary season. On Friday, the Arizona senator’s campaign used that cordial campaign trail language in a Web ad promoting McCain’s White House bid.
“Supporters of Mike Huckabee are attacking John McCain,” reads the screen at the start of the 30-second spot. “What does Mike Huckabee say about John McCain?”
Then footage of Mike Huckabee himself is shown: “Sen. McCain, no matter what anyone may say, is a genuine conservative. … John McCain is a hero in this country. He's a hero to me.
"If you look at his record, he's got a solid record on things that really matter. He's pro-life, he's strong for our country's defense and security…. John McCain is a true, honest-to-God American hero.”
“If you want the truth about John McCain,” reads the screen, “just ask Mike Huckabee.”
The campaign says “Trust Huckabee” is a response to the wave of robo-calls from pro-Huckabee group Common Sense Issues, which says it is planning to make a million calls to South Carolina voters before Saturday’s primary that attack McCain on abortion and immigration.
