(CNN) - A roundup of comments on the Sunday political talk shows, compiled by the CNN Wire:
On Obama's selection of Sen. Joe Biden as VP:
"I don't think (Obama) is ready to be president. And when you're commander in chief, you shouldn't be having to select a mentor to help you with that role." –Minnesota Gov. Tim Pawlenty, considered a potential VP for McCain, on CNN's "Late Edition"
"It was an honor to be in that final two or three. You know, I don't think you'd be there unless they concluded you had a lot of positive things to offer and probably not too many negatives." -Sen. Evan Bayh, whom Obama considered for VP, on CNN
"It always seemed like kind of a longshot to me, but it was really, really nice to be mentioned." -Virginia Gov. Tim Kaine, also considered for VP, on "Fox News Sunday"
"We didn't hire him for his stunning good looks. We hired him for his judgment to lead this country if something happens to Barack Obama, and the judgment and the advice that he'll give the next president of the United States." -Obama campaign spokesman Robert Gibbs, on Fox
"It's really a process, for me, that was wonderful to be part of, because I really came away thinking, once again, that there are so many great people in public service." -Caroline Kennedy, co-chair of Obama's VP search committee, on NBC's "Meet the Press"
"John McCain is going to pick somebody next week, and the odds are that either that person will have said things about John McCain." -Obama campaign adviser Anita Dunn, on CNN
On Obama not choosing Clinton
"Senator Obama has made a choice more out of weakness than strength... The strong choice would have been Hillary Clinton. The obvious choice would have been Hillary Clinton. She had 50 percent of the Democratic vote... You almost have to go to extraordinary lengths to avoid her as the vice presidential pick of the party." -Former Republican presidential hopeful Rudy Giuliani, on ABC's "This Week"
"The first person that he sat down and talked to at all about this vice presidential issue was Senator Clinton. They had a discussion back in early June about it." -Obama campaign strategist David Axelrod, on ABC
"I don't think there's any question at all that the Clintons are wholeheartedly behind Barack Obama. They want to see a Democrat elected president of the United States." -Kansas Gov. Kathleen Sebelius, on CBS
"She ran a fantastic campaign. I'm a huge admirer of hers." -Caroline Kennedy, on NBC
On McCain's ad about why Obama did not choose Clinton
"This ad will have a three-day life span. When Hillary Clinton speaks on Wednesday night, she will blow this ad out of the water." -Pennsylvania Gov. Ed Rendell, on CBS
"This campaign is not about Barack Obama and Hillary Clinton. This campaign is about George Bush and four more years of George Bush under John McCain. That message is going to echo clearly from this platform." -Rep. Jesse Jackson Jr., on CBS
