After four years in which he has alternately helped -- and miffed -- the White House, Vice President Joe Biden told CNN that his role as the deal-closer is clearly his most comfortable yet.
"I have spent a lot of time in this town. And I have personal relationships with people I strongly disagree with, but there's trust. And so I'm a logical person, a logical person to, as they say or you guys say, close the deal," Biden told CNN chief political analyst Gloria Borger in an exclusive pre-inaugural interview.
Biden cut the last-minute deal last month with Senate Minority Leader Mitch McConnell that averted going over the fiscal cliff -- after President Barack Obama's negotiations with House Speaker John Boehner failed. He was given the high-profile task of putting together the administration's sweeping gun control proposals and will play a major role in pushing them through Congress.
He is quick to emphasize that he was not undercutting the president when he reached deals with congressional Republicans.
"I have his complete support for what I'm saying, because I know what he wants, No. 1," Biden said. "It's the president, not me."
Obama and the vice president ran against each other for the 2008 Democratic nomination, and Biden said that helped forge a relationship.
"So when we got into this deal, we didn't have what other administrations have had, where the vice president and the president have a different take on the major issues of the day. We're totally simpatico," Biden said.
He told Borger that he never had any problem with any assignment he was given in the first term, when he was tasked with overseeing the $787 billion stimulus program, cutting several key fiscal deals with congressional Republicans once they took control of the House of Representatives in the midterms and leading the effort to end the U.S. military presence in Iraq.
In the second term, one of his major duties will be to help get congressional approval for the most far-reaching gun control legislation in decades. After dozens of meetings with more than 120 groups spanning the various issues related to gun violence, he led the inter-agency effort that came up with the specific proposals.
Biden and Obama know they will have to mount a major public relations campaign to try to overcome the strength and opposition of the National Rifle Association.
"There's a growing consensus in this country, a growing consensus among even sportsmen and other groups, about everything from who should own a weapon ... and what information should be available," he told CNN, saying he believed it would be easier to pass this type of legislation in the wake of the elementary school shootings in Newtown, Conn.
Biden, a major gun rights proponent who has gone up against the National Rifle Association for decades, was the major reason the 1994 assault weapons bill passed.
Asked if he thought the NRA is stoking fear against the president, he responded, "Look, I think the NRA's reaction -- overreaction -- is a reflection of the vulnerability of their position."
Biden is also expected to be one of the key players in coming fiscal fights: automatic spending cuts set to take effect in a month, funding the government and the debt ceiling. House Republicans just signaled they would support a three month extension.
The vice president said that is a hopeful sign that the GOP would not allow the country to default on its debts.
"The Republicans aren't going to do that. They've finally figured it out. All this bluster about you're going to renege on the debt," he said. "They will not because there are more responsible people in that party than irresponsible. So it's not going to happen."
Biden said he hoped there is still a path forward to allow the White House and congressional leaders to reach agreement on a major deficit reduction deal -- one that has so far eluded them despite optimism in the past.
"So we ought to be able to, in the next three months, finish out that grand bargain to get us to the point of ... where debt to GDP (gross domestic product) is about 3 percent," he said. "Every economist, left, right and center, says that -- when that happens, the economy grows. I think we'll get there."
As the president and vice president have worked to achieve many of the administration's major goals, the two have had some disagreements -- Biden did not agree that the timing of the mission to kill Osama bin Laden was right, and the vice president got out in front of his boss when Biden voiced support for same-sex marriage on "Meet the Press" last May.
"We sometimes disagreed on tactics as to how to proceed to try to get what he wanted done, which I've agreed with, but we've never disagreed on policy. And even the so-called discussion about, you know, my saying I was comfortable with gay and lesbians and relationships, I knew his positions," Biden said.
When Borger asked about those specific comments, he recounted how the president reacted.
"I walked into the office and he got up, smiled, gave me a big hug and he said, 'Now, I'll tell you what, man, that's one of the things I like about you, you say what's on your mind,' " the vice president recounted.
He recently told The New York Times it did cause "a little apoplexy" around the White House.
"It did, but not with him. Not with him."
It was with the president's staff. Some of Biden's candor has at times has not gone over well with White House officials.
