Andy Martin, GOP Senate Candidate, Calls Opponent Mark Kirk A "De Facto Pedophile" (AUDIO)

An already ugly race in the Republican primary for Illinois' 2010 Senate seat only got uglier Wednesday, as candidate and noted mud-monger Andy Martin released an ad calling his opponent, Rep. Mark Kirk, a "de facto pedophile."

Listen to the ad below.

Martin's campaign suggests that Kirk knew about Rep. Mark Foley's indiscretions with young male pages, and allowed them to happen. As such, Martin claims, Kirk "should be disqualified from holding public office."

The 60-second radio spot was accompanied by a lengthy press release from Martin's campaign explaining the claim. It's the second in a series of what he calls "bunker busters," accusations that are meant to explode Kirk's hidden secrets and campaign hopes.

A week ago, Mr. Kirk announced a "solid rumor" that Kirk was homosexual. That announcement led to his official rebuke by the Illinois GOP, whose chairman Pat Brady called his claims "bizarre" and "hate-filled."

But no amount of flak is likely to slow down Mr. Martin. He made a name for himself as one of the early proponents of the "birther" movement; he claimed that President Obama locked his white grandmother in a closet to hide his mixed racial background; and he once described a bankruptcy judge as "a crooked, slimy Jew, who has a history of lying and thieving common to members of his race."

The third "bunker buster" is expected next week in anticipation of the Feb. 2 primary.
