Having picked up at least 13 seats for his party, Chuck Schumer is calling it quits. From the New York Times:

Mr. Schumer, the senior senator from New York, is expected to turn the Democratic Senatorial Campaign Committee over to Senator Robert Menendez of New Jersey — keeping control of the campaign operation close to Wall Street, party officials said.

In 2006, Mr. Schumer led the successful Democratic drive to win back control of the Senate from the Republicans. The Democrats picked up six seats that year, bringing them to a razor-thin 51 to 49 majority, thanks to two independents who organize with the Democrats.

In recognition of his efforts, Mr. Schumer was named to a new leadership position as the No. 3 Democrat in the Senate, after the majority leader, Harry Reid of Nevada, and the whip, Richard J. Durbin of Illinois.
