Mitt Romney’s vice presidential pick will likely not come until the family horse, Rafalca, is finished competing in dressage at the London Olympic games. That can only mean one thing, Stephen Colbert said Tuesday: Romney has chosen Rafalca as his running mate.

“It’s a historic choice, like Sarah Palin,” Colbert said. “Like Palin, Rafalca’s female, also doesn’t read newspapers and has completed the same number of terms as governor. Great VP pick.”
