Peanuts, cracker jacks and clowns? That's right - Ringling Brothers and Barnum & Bailey Circus will be on hand at the Nationals game against the Phillies Wednesday evening. The appearance will promote current circus performances at the Patriot Center in Fairfax, Va., through April 24. At Nationals Park, the Ringmaster, Johnathan Lee Iverson, will sing the national anthem while Tom, Abe, George and Teddy will race against circus clowns in the GEICO President's Race.
