Rafalca, the horse famously co-owned by Ann Romney and her dressage trainer Jan Ebeling, was eliminated from the Olympic dressage competition Tuesday.
Rafalca earned a score of 69.317, which bumped her out of the top 19.
Ann Romney was in the stands of Greenwich Park earlier today and despite the poor showing by her horse, said she was very proud.
"It was wonderful," Romney told the Associated Press. "She was elegant and consistent again. We just love her."
Ebeling told the AP he was disappointed with the results. "I wish the score would have been higher," Ebeling said. "I'm really happy with the horse."
Only the top 18 riders continue on to the freestyle portion of the competition on Thursday. In the previous Olympic test Aug. 2, Rafalca and Ebeling earned a score of 70.2.
Ebeling and Rafalca danced to a mix of traditional and fast-paced music, and Ebeling took off his top hat and beamed at the conclusion of Tuesday's ride in Greenwich Park. The weather looked chilly as audience members bundled up. But there were still plenty of American flag wavers in the stands to cheer them on.
They faced stiff competition from many of the riders, especially some of the "stars of dressage," including Britain's Charlotte DuJardin and her horse Valegro, who earned a stunning 83.66 last week and hope to bring home Britain's first gold in dressage ever.
Patty Lasko, the editor of Dressage Today, told ABC News that sometimes those watching see things the judges miss, and she thought Ebeling and Rafalca's performance last week was "wonderful," emphasizing that any score above 70 percent means a strong performance, especially for first-time Olympians.
"They were great. ... Those of us who are not judges don't always see what they see or go with what they seem is right, but I thought he did wonderful," Lasko told ABC News. They should be very proud, and that score is a very credible score."
Of course, it's not just dressage fans closely monitoring how Rafalca performs, it's veepstakes watchers, too. It was believed that Mitt Romney would not pick a running mate until Rafalca and Ebeling were out of the competition so that Ann Romney could return to the United States. The photograph of the two families - the Romneys and the running mate - side by side is something a campaign would likely not pass up.
Romney, who has said riding helps relieve her multiple sclerosis symptoms, said she was "thrilled to death" after their first performance. She was diagnosed with MS in 1998 and began riding again, after initially riding as a child, soon after.
Although it is celebrating its 100th year as an Olympic sport, dressage, also known as horse ballet, was until recently relatively unknown in the U.S. Not anymore. The attention the Romneys have brought to the sport even had satirist Stephen Colbert calling it the "sport of the summer." The equestrian discipline gained more attention than any of its enthusiasts could have anticipated when Rafalca made the Olympics cut in June.
Ebeling and Romney co-own the German-born 15-year-old Oldenburg mare with Beth Meyer. Ebeling, a German native, became a U.S. citizen in 1998. Before competing, he doesn't let anything shake his focus -- not the campaign and not the media attention. He doesn't even speak to anyone on performance days.
