U.S. Rep. Marilyn Musgrave's latest television ad subjects a Betsy Markey stand-in to a lie detector test about Markey's business dealings.

Meanwhile, a new Democratic Congressional Campaign Committee television ad released over the weekend hits U.S. Rep. Marilyn Musgrave for "putting special interests ahead of" U.S. troops.

In Musgrave's new ad, a blonde who vaguely resembles Markey is hooked up to a lie detector.

"Did you violate Senate ethics rules to make millions in government contracts for your family business?" the questioner asks.

"No," the blonde says, as the machine beeps, "false detection."

In the ad, "Markey" also fails questions about whether the Senate ethics committee told her to completely separate herself from her company if the company sought government contracts, and whether she falsified information on over 60 contracts worth more than $2.7 million.

Both the General Services Administration and the U.S. Senate Ethics committee  general counsel have said Markey broke no rules by co-owning her information technology business for several months after taking a staffer job with U.S. Sen. Ken Salazar's (D-Denver) office in 2005.

The DCCC ad continues their theme of connecting Musgrave with ‘special interests."

"When Marilyn Musgrave sides with the special interests, who suffers? Our troops," an announcer states in the ad.

The ad states that Musgrave voted against a $1,500 combat bonus for troops, against a new GI bill, and against health care for the national guard. But she "accepted $14,000 in pay raises, and voted Wall Street billions in tax breaks."

Musgrave accepted the pay raise - as did virtually every other member of Congress, according to the Coloradoan. Musgrave has said charges that she doesn't support veterans are untrue and are among the most hurtful claims against her in this campaign.

The DCCC ad cost about $9,000 to produce, according to the Fort Collins Coloradoan. The group has reserved about $300,000 worth of air time during the last week of the election, according to the Coloradoan.
