(CNN) – Her husband has already made two bids for the White House, but Jill Biden said in an interview airing Thursday she wasn't ruling out a third attempt.
"I think Joe would be a great president. I supported him twice. In 1987, I was out there campaigning. The last election I was out there campaigning. Of course, Barack must have thought he would be a good president, too, or he wouldn't have chosen him as vice president," Biden told CNN's Soledad O'Brien on "Starting Point."

Biden was echoing remarks she made earlier in the week, when she told NBC she "wasn't sure" if the 2012 campaign would be her husband's last.
The vice president, who would be 73 in four years, stirred speculation in October when he left the door open to a 2016 campaign.
"I'll make up my mind on that later," Biden said in an interview on CNN's "State of the Union." "I'm in one of the, probably the best shape I've been in in my life … I'm doing pretty well. I'm enjoying what I'm doing, and as long as I do, I'm going to continue to do it."
In her CNN interview, Jill Biden weighed in on a recent Pew study showing political polarization at a 25-year high. The second lady pointed to a shift in the Republican Party to explain the phenomenon.
"I think the parties are really disparate and probably the Republican Party has gone way far right than it has gone before," Biden said. "It certainly is not the Republican Party I grew up with."
The 2012 election, Biden said, would provide Americans a clear choice.
"I think that Mitt and Barack are on totally different paths," she said. "And, you know, you've got clear choices. That's what I think. Of course, I think our choice is the best."
CNN's Ashley Killough and Kevin Liptak contributed to this report.
Biden would make a good president. He's in touch with mainstream America. He's very much aware of the problems the majority of Americans face and wants to help fix them. He's respected at home and abroad. And he's a democrat which means he's FOR American and not for the party like the GOPers are.
Dr. Biden is so smart and well spoken. She filled. Huge hole in the Vicd President's heart after the crash who killed some od his family members. She is quite a woman.
Hold your nose, have patience....let us tackle November first......focus on Florida, WI, OH, they may rig election just like Bush did....watch. This is getting worst than 3rd world nation. God bless!!!
More like Jill Biden is promoting her husband during this run than anything else. The Bidens are both great examples of public servants FOR the people. Good luck to both of them during this run.
Second lady that's the first time I have ever heard that phrase before must be a new thing what a joke.
Who is the third and fourth lady they have to be out there.
LOL – she must be dreaming – I'm a Democrat, but there's no way Biden will ever make it, to the commander in chief's Job. Unfortunately, Romney will be our next Prez.
LOL! This is a guy who is extremely close to being kicked off the ballot as VICE PRESIDENT! Please, Democrats, let Biden get the nomination in 2016, it will be the best election ever!
You're wrong about you husband and wrong about the best choice in 2012.
