Obama's top advisor appeared on FOX News Sunday:
WALLACE: I want to show you a recent poll, and it found that on the question, "Who offers hope for the future," Obama beats McCain 54 percent to 19 percent. But on the question, "Who would be a better commander in chief," McCain beats Obama 53 percent to 25 percent.
In that sense, was part of the calculation voters have a concern about Obama's experience, about the — the amount of time he has, and is he ready to be commander in chief, and Joe Biden helps you in that area?
GIBBS: Well, look. I think — I think Senator Biden, again, has unparalleled foreign policy experience. And I think if you look at not just what was said yesterday by Democrats about this pick, but look what was said by Republicans.
Senator Dick Lugar of Indiana, the chairman of the Foreign Relations Committee, Senator Chuck Hagel, an unparalleled expert on defense policy, Senator Arlen Specter, another Republican, this time from Pennsylvania all spoke very highly of the choice of Joe Biden.
Look, I think what you have together is two people that have the judgment to lead this country, the judgment and the experience. And I think it will make a big difference in the fall. We're very happy with our pick. We think — again, unparalleled foreign policy experience.
WALLACE: But what about change? Joe Biden has actually been in the halls of Congress 10 years longer than John McCain has. So this whole message about change, we're going to shake up the way things are done in Washington — doesn't that go out the window?
GIBBS: No, because again, as I said to you earlier, Joe Biden works in Washington but he doesn't live there. He goes — every night, he goes home on an Amtrak train, where he knows the names of the conductors, to his wife and family in Delaware.
I think he's somebody who never has forgotten where he's from. He was born in Scranton, Pennsylvania. He's never forgot that middle- class background. You know, he's — and, Chris, he knows how many houses he owns. So I think he's a down-to-earth kind of guy.
I think he — again, I think you've got a ticket that says a lot about change in this country because both of these candidates understand, and they've understood for a long time, we can't have four more years of the same George Bush, John McCain policies that have led this country into the direction that we're in now.
