The call is still going on, but Sen. Graham has already said some interesting things.
... Regarding McCain's qualifications: "I would argue Senator McCain is the most qualified to be Commander-in-Chief since Eisenhower."
... More: "Bob Dole was a war hero, he didn't win the election. Nobody thinks John McCain will win the election because he was a P.O.W."
... On Gen. Clark's comments: "No matter how he sugar-coats it, he's trying to question John's service."
... On Obama's response to Clark's comments: "Today, they're pretty quiet when he reiterates an attack."
Lt. Col. Swindle just began speaking. He referred to Keith Olberman and Mika Brzezinski as Obama surrogates.
Regarding Clark, he said: "He's failed as a presidential candidate ... a great ego."
Both Graham and Swindle stress McCain's experience as a Senator as being equally important to his military experience.
Swindle points out that McCain has never said that being a P.O.W. qualifies him to be president.
Regarding whether or not there was a concerted effort to attack McCain's military experience, Swindle said: "I happen to believe that six or seven people making comments like this doesn't happen by accident."
Update: HotAir's Capt. Ed Morrissey has more.
