Washington (CNN) - Sen. Michael Bennet of Colorado will serve as the chairman of the Democratic Senatorial Campaign Committee for the 2014 cycle, Senate Majority Leader Harry Reid announced Tuesday.
The DSCC, a group tasked with getting Democrats elected to the Senate, was chaired by Sen. Patty Murray of Washington in the last cycle, one marked by a net gain of two seats for Democrats in the upper chamber.

"Michael is one of the brightest rising stars in the Democratic Party, and he is exactly the right person to lead our efforts over the next two years," Reid said in a statement. "Not only does Michael know how to win tough races, he has the trust and loyalty of the entire Democratic caucus behind him."
Guy Cecil will continue to hold his position as executive director for the DSCC. Prior to leading the committee, Cecil served as Bennet's chief of staff during the senator's 2010 victory. Bennet had been appointed to the Senate seat in 2009 by the state's governor after Ken Salazar vacated the seat to serve as the U.S. secretary of the interior.
"I couldn't be happier that Guy has agreed to continue at the DSCC," Reid said in the statement. "He has been an outstanding leader in our Party and provided strong strategic leadership in 2012. He has my full confidence."
Of the four campaign committees, the DSCC was the final group to announce its leadership positions.
Thanks to their big victories in the 2008 election, the Democrats will be defending 20 of the 33 Senate seats up for grabs in 2014.
If it sounds familiar, it is. Thanks to their success in the 2006 midterms, the Democrats were forced to defend 23 of the 33 seats up for grabs in last month's elections. They expanded their majority by two and will hold a 55-45 advantage starting in January.
Among the most vulnerable Democratic senators up for re-election in 2014 are (in alphabetical order): Mark Begich of Alaska, Max Baucus of Montana, Kay Hagan of North Carolina, Tim Johnson of South Dakota , Mary Landrieu of Louisiana, and Mark Pryor of Arkansas.
Democrats may also have some open seats to defend. Sen. Frank Lautenberg of New Jersey is an obvious candidate to retire. He'll be 90 by Election Day 2014. And Jay Rockefeller of West Virginia will be 77 by the midterms.
