U.S. Senate candidate Andrew Romanoff released a television ad Friday that sent Colorado’s Democratic establishment, including the governor and attorney general, into a mad dash of denunciations that served to defend his primary opponent.

The attack ad features footage from a well-known, decade-old John Hickenlooper ad in which the then-candidate for governor showers with his clothes on. As clips of Hickenlooper in the shower play, so do recent headlines about Hickenlooper’s ethics travails and racial gaffes.

“You gotta ask yourself: Why does John Hickenlooper take so many showers?” a narrator asks. “I mean, he’ll never wash out the stain of oil and gas money. Maybe it’s the convictions for taking illegal gifts or being held in contempt. Scrub harder, Hick.”

The narrator then suggests Hickenlooper would be a risky nominee against Sen. Cory Gardner, a Yuma Republican.

The ad will run statewide on television and online until the June 30 primary between the two Democrats, according to the Romanoff campaign.

“Cory Gardner, Mitch McConnell and now Andrew Romanoff are spending nearly $2 million attacking John,” said Melissa Miller, a Hickenlooper spokeswoman.

Within hours of its debut Friday morning, Colorado’s most prominent Democrats had denounced the ad. They’re coming to the defense of Hickenlooper in the intra-party fight as he attempts to avoid a disastrous upset loss amid a month of ethics violations, a contempt citation and gaffes.

“I’m disappointed that Andrew Romanoff has chosen to throw mud and attack John Hickenlooper instead of focusing on his own vision and record,” said Gov. Jared Polis, who had previously vowed to remain neutral in the race, in a statement sent from Polis’ campaign. He urged Romanoff to reconsider airing the ad.
