(CNN) – President Barack Obama discussed his frustration with gridlock in Washington, saying his "biggest disappointment" in his nearly four years in office has been the failure to oversee change in the nation's political climate.
"My biggest disappointment is that we haven't changed the tone in Washington as much as I would have liked," Obama said in a CBS News interview that aired Sunday.

Asked if he bears any blame for the stalemate, Obama said the buck stops at his desk.
"I think that, you know, as president I bear responsibility for everything, to some degree," he said on CBS' "60 Minutes."
Throughout the presidential campaign, Mitt Romney's campaign and Obama’s critics have dogged the president for failing to get certain legislation passed in recent years, while Team Obama responds by faulting congressional Republicans for not compromising.
The tension has especially heightened as Congress faces a looming, end-of-the-year deadline to avoid the "fiscal cliff," a massive amount of tax hikes and spending cuts set to take place at the beginning of 2013 if Congress fails to act. Lawmakers on both sides have already showed signs of firm partisan division on the issue.
Obama's comments aired days after the president drew criticism from Romney over separate remarks about change in Washington, comments that suggested a slight tweak in Obama's 2008 ideals of "hope" and "change."
"The most important lesson I've learned is that you can't change Washington from the inside. You can only change it from the outside," Obama said Thursday afternoon at a presidential forum the candidate taped to run on the Spanish-language network Univision.
Within hours, GOP presidential candidate Mitt Romney seized on the remarks, argued Obama had thrown up the "white flag of surrender," and vowed to make that change, himself.
"His first two years he had a Democratic House, Democratic Senate, he got to do whatever the heck he wanted to, but he says he can't change it from the inside. Well, I will," Romney told a Sarasota, Florida, crowd.
During his CBS interview, Obama reiterated ways he would recruit the American people to help him fix the nation's capital.
"Something that I'd really like to concentrate on in my second term is being in a much more constant conversation with the American people so that they can put pressure on Congress to help move some of these issues forward," Obama said.
Last summer, the president used such a technique, directly urging Americans in a primetime speech to call their representatives in Congress during the intense budget battle and tell them to vote for the debt ceiling increase. Responding, Americans dialed in and caused massive phone-line jams on Capitol Hill.
In the Sunday interview, Obama also offered some ways in which he has seen change, most notably the passage of health care reform.
"And so change has happened and positive change for the American people. I'm the first one to confess that," he said.
However, when it comes to shifting from a "political slugfest" to a climate more focused on "problem solving," Obama acknowledged he hasn't "fully accomplished that."
On the same CBS program Sunday, Romney agreed the problem ultimately falls on the president's shoulders and offered his own approach to resolving the partisan impasse.
"Leadership is not just working with your own party, but working with both parties. And I learned that. I was governor of a state with a legislature 87 percent Democrat," Romney said. "I realized I was going to get nothing done unless I had a relationship– a respect, and trust with– with the members of the– of the opposition party."

Don in Albuquerque,Dude, your idea of liberal and my idea of liberal are two different things. All of a sudden Lincoln was a liberal I suppose Reagan was a liberal too. This is exactly what I'm talking about. The smug arrogance of imagined intelligence. I would argue that Social Security helped to make us less financially responsible. OMG I can hear the hollering now.
Funny thing is... No conservative ever takes responsibility for a thing and they in their minds never make any mistakes. They are all perfect... NOT!
