RACHEL MARTIN, HOST:
For a string of retiring senators, the acrimony over the fiscal cliff is just the latest example of partisan polarization that's been on the rise in recent years. As NPR's David Welna reports, this was noted - sadly - by the lawmakers as they bid their colleagues farewell this past week.
DAVID WELNA, BYLINE: At 88, Hawaii Democrat Daniel Akaka is the most elderly of the six Democrats and seven Republicans who won't return to the Senate next year. Akaka is a quiet and gentle man, and he had some Pacific Islander advice for his colleagues as he prepared to leave the Senate after 24 years:
SENATOR DANIEL AKAKA: In Congress and in our nation, we're truly all together in the same canoe. If we paddle together in unison, we can travel great distances. If the two sides of the canoe paddle in opposite directions, we will go in circles.
WELNA: Akaka is retiring by choice, but Indiana's Richard Lugar, who at 80 is the Senate's oldest Republican, hoped for a seventh term. A moderate who's a foreign policy expert, Lugar lost his primary to a Tea Party-backed challenger, who in turn lost the election to a moderate Democrat. Last week, Lugar told colleagues their prime responsibility is to follow their own best judgment.
SENATOR RICHARD LUGAR: Too often in recent years, members of Congress have locked themselves into a slate of inflexible positions, many of which have no hope of being implemented in a divided government.
WELNA: And as he bid his farewell after four terms in the Senate, Democrat-turned-independent Joe Lieberman of Connecticut had this advice for colleagues: Put country and constituents ahead of the dictates of party and ideology.
SENATOR JOE LIEBERMAN: I regret to say as I leave the Senate that the greatest obstacle that I see standing between us and the brighter American future we all want is right here in Washington. It's the partisan polarization of our politics.
WELNA: Like Lieberman, Nebraska Democrat Ben Nelson preferred retirement to a tough re-election battle. In his farewell, Nelson made no bones about frequently crossing the political aisle to get things done.
SENATOR BEN NELSON: Congress needs to change its math. By that, I mean members of Congress should be more concerned about addition and multiplication, and less involved in division and subtraction that seems to overtake this institution at times.
WELNA: After 26 years in a Senate that has not passed one budget in the last three years, Budget Committee Chairman Kent Conrad is also calling it quits. Last week on the Senate floor, the North Dakota Democrat said too much time is spent there seeking partisan advantage and too little actually trying to solve problems. But Conrad added that he's not one of those who leaves the Senate as a critic.
SENATOR KENT CONRAD: I leave this institution with enormous respect. The United States Senate is the greatest deliberative body in the world. And the vast majority of my colleagues, I sincerely believe, are serious-minded and have the best interests of the country at heart.
WELNA: Conrad has long hewed close to the political center, so too has Maine's Olympia Snowe. The Republican maverick grew so frustrated with Senate gridlock, she decided she'd had enough.
SENATOR OLYMPIA SNOWE: I worry we are losing the art of legislating.
WELNA: In her valedictory, Snowe said she's seen the potential of government as an instrument for common good, but she's also experienced its capacity for serial dysfunction.
SNOWE: And as I've traveled throughout Maine and America, even overseas, people would stop me and ask me what has happened? Has it always been this way? And I tell them, I'm so passionate about changing the tenor in Congress because I've seen that it can be different. It hasn't always been this way, and it absolutely does not have to be this way.
WELNA: Still, the departure of Snowe and other political moderates may not bode well for a Senate where little gets done without bipartisan cooperation. David Welna, NPR News, the Capitol.
