(CNN) – The liberal group MoveOn.org will run a thirty-second television spot in battleground states mocking Rafalca, the dressage horse competing at the London Olympics that is co-owned by Ann Romney.
The group said the total buy amounted to five figures, which will be used to air the ad in Nevada, Ohio and Pennsylvania.

The ad is told from the perspective of the horse.
"My name's Rafalca, the Romney's dressage horse," the ad begins. MoveOn.org uses a poorly-executed English accent as the voice of the Romney's horse.
"You might have seen me execute 'leg yields' and 'flying changes,'" the ad continues, using terms from the sport of dressage. "How do I pull off such grace and athleticism while looking so good? Maybe it's because the Romneys spend $77,000 per year on my upkeep."
The ad comes to a grim conclusion, stating: "After Mitt Romney repeals health care and ships your jobs overseas, I daresay your life won't be nearly as pampered as mine. After all, you're not one of his horses."
In a statement, MoveOn.org's executive director said the group wasn't lampooning the Romney's care of their horse – just the expense of it.
"There's nothing wrong with taking good care of a horse, but there's something messed up about a millionaire who spends twice what most Americans make in a year caring for a horse, but wants to take away people's health care and offshore their jobs," Justin Ruben wrote. "We're rooting for Rafalca and all of our Olympians to bring home the gold, but we're sure not rooting for Mitt Romney to send jobs overseas. Voters had best steer clear of Romney unless they're looking for a ride on a one-trick trickle down pony."
In mid-July, the Democratic National Committee briefly used video of the Romney's Olympic-bound horse to portray the candidate as "dancing around the issues," but later discontinued using Rafalca because it could be seen as offensive to the GOP candidate's wife.
Ann Romney began riding horses when she was diagnosed with multiple sclerosis in 1998, and has said the sport has helped lessen the symptoms of the inflammatory disease.
