Politics played a powerful role in Senate Democrats' committee assignments, announced on Wednesday, with many of the senators-elect who survived tough races given plum spots in powerful committees as a reward.

Bennet will give up his spots on the Banking and Aging committees to make time for his new responsibilities on the Finance Committee and as DSCC chairman, which will require him to travel the nation recruiting candidates and raising millions to protect the Democratic majority in the Senate. 

That task looks as daunting as it did two years ago, with 20 Democrats up for reelection — many in states Mitt Romney won this year — and only 13 Republican seats up in 2014.

Warren was the chief architect of the Consumer Financial Protection Bureau (CFPB), which was created by the Dodd-Frank financial reform law, and has long been a critic of Wall Street and big banks. She was given a seat on the Banking Committee, which has jurisdiction over Wall Street regulation and oversight.

She'll also serve on the Aging and Health, Education, Labor and Pensions committees.

She managed to pull out a surprise win against Rep. Rick Berg (R) on Election Night, despite Romney's sweep of the state by about 20 percentage points.

Farming is one of North Dakota's main economic drivers, and she pledged during her campaign to nab a seat on the Agriculture Committee, which oversees the creation and implementation of the farm bill.
