Need proof this is an election year for U.S. Sen. Bob Casey Jr.? Well he just took a principled stand in defense of...the rights of Philadelphia Phillies fans to travel to the nation's Capitol to root against the Nationals. Casey, in a letter to Nationals owner Theodore Lerner, decries a new team "gimmick" that gives priority to in home game ticket sales to customers from Washington, D.C., Maryland and Virginia.
