Olivia Wilde joins 'Dogs against Romney' campaign


Wilde, best known for the TV show "House" and movies such as "Cowboys & Aliens," plans to campaign for President Obama, as she did in 2008. She said she would not characterize herself as "disappointed" in Obama, but added that the top three things she wants to hear the president address are drones in Pakistan, drug policy and Guantanamo. 

"I think those are the topics that will come up during the campaign, and I think those are the conversations that need to happen," she said. "So I'm not a blind supporter, but I'm definitely in favor of having these discussions."

Also on the show, Wilde reluctantly admitted that she is a horseback rider and, much like Ann Romney, has practiced dressage.

"I have, I did!" she said, leading to Colbert's suggestion that she has more in common with the Romneys than the Obamas. The Romneys have been criticized for enjoying an expensive hobby, and Colbert has previously mocked the Olympic sport of dressage as elitist. 

On Tuesday's show, he took credit for the Olympic qualification of Rafalca, a horse co-owned by Ann Romney. 

Ann Romney, over the weekend, addressed Colbert's remarks about dressage, calling them "hilarious."

"I think it will open up a lot of things for dressage," she said, according to the New Jersey Star-Ledger. Ann Romney and other dressage fans posed at the Olympic qualifying event wearing "Dressage is No. 1" foam fingers -- mimicking the type of fan memorabilia typically only seen at more large-scale sports events -- that were distributed by the U.S. Equestrian Federation.
