The campaign arm of U.S. Senate Democrats has organized a joint fundraising committee to help it raise money along with the 2010 campaign of Colorado Sen. Michael Bennet.

Colorado Senate 2010 was organized by the Democratic Senatorial Campaign Committee with the Federal Election Commission on Sept. 8. The DSCC and Bennet’s campaign committee will share the proceeds.

The fundraising help comes as Bennet, who was appointed to the Senate in January, prepares to stand for election next year against determined challengers in both parties, first from former state House Speaker Andrew Romanoff in a Democratic primary.
