Freedom’s Watch, a conservative advocacy 501(c)(4) organization, is set today to hit Colorado’s airwaves with a television spot critical of Democratic Senate nominee Rep. Mark Udall.

The 30-second spot uses humor to accuse Udall of supporting federal funding for a “Department of Peace” at the expense of funding for the troops. Freedom’s Watch characterized the ad buy as being in the “high six figures.”

The ad is set to go up today, come down Thursday in observance of the seventh anniversary of the Sept. 11 terrorist attacks and then go back up Friday for one week.

“Welcome to the Department of Peace,” an actor dressed as a 1960s-era protester says as the ad opens, as he points to a Volkswagen Bus from the same time period.

“Sure, it looks like a van, but with Congressman Mark Udall’s help, it really could happen. Udall wanted to spend billions on a Department of Peace and a Peace Academy.”

The spot is scheduled to run on broadcast and cable television in the Denver, Colorado Springs and Grand Junction media markets.

“Bob Schaffer’s special interest cronies have run millions of dollars in attack ads against Mark Udall, but they haven’t moved this race at all because Coloradans just don’t believe Big Oil Bob’s lies,” Matthew Miller, spokesman for the Democratic Congressional Campaign Committee, wrote in an e-mail.
