ABC News(WARSAW) -- The success of Ann Romney's dressage horse Rafalca in the London Olympics could determine when Mitt Romney announces his running mate.
As Mitt Romney prepares to head back to the states tomorrow evening after several days abroad, the frenzied speculation over who he will choose to be his running mate will reignite after a momentary pause.
But not so fast, veepstakes trackers.
One person who isn't heading back to the U.S. quite yet is Ann Romney, who will return to England to see her horse compete on August 2 and 3. Depending on how the horse performs, he could show again on August 8 and 9, according to Mrs. Romney's spokeswoman Sarah Haley.
That means Ann Romney may not be back in the United States for at least another week. It's unlikely that the presumptive GOP presidential nominee will announce his running mate - perhaps one of the most important moments of his campaign - without his wife, whom he often refers to as his "sweetheart," by his side.
