Democratic Congressional Campaign Committee’s independent expenditure arm is announcing plans to air competing radio advertisements targeting Freedom’s Watch, the conservative advocacy group heavily funded by Las Vegas billionaire Sheldon Adelson.

The ads are set to begin airing Friday. A DCCC spokesperson did not provide information on the size of the ad buy.

“Democrats will not allow Freedom’s Watch to mislead voters,” said Jennifer Crider, a spokeswoman for the DCCC.

The announcement comes one day after Freedom’s Watch announced plans to launch radio and television advertisements targeting Democrats nationwide.

The DCCC’s radio advertisements will be airing in the ten congressional districts where Freedom’s Watch is airing radio ads of their own: Idaho’s First Congressional District, Louisiana’s Sixth Congressional District, Michigan’s 7th Congressional District, Missouri’s 6th Congressional District, New Hampshire’s First Congressional District, New Mexico’s 1st Congressional District, New York’s 29th Congressional District, Ohio’s 15th Congressional District, Ohio’s 16th Congressional District, and Pennsylvania’s 10th Congressional District.

The DCCC’s decision to air radio spots challenging Freedom’s Watch comes on the heels of the committee’s launch of a Web site hammering Freedom’s Watch for its ties to the Bush administration.

Ed Patru, a spokesman for Freedom’s Watch, said he would not comment on the ads without knowledge of their content.

But he said, “We'd like to hear the DCCC run ads calling Members to cut their five-week summer vacation short and get back to Washington to vote on legislation to lower gas prices. I doubt the country will be so lucky.”
