Congressman Lou Barletta – the Republican challenging Senator Bob Casey in the general election – will make a stop in Beaver today as part of a statewide bus tour. Barletta will be at Mario’s Woodfired Pizzeria on Third Street at noon today for a meet-and-greet with voters in the latest stop on his “Red, White and Lou” tour. Prior to coming to Beaver, Barletta will be in New Castle this morning. Barletta defeated State Representative JIm Christiana in the Senate GOP primary but is trailing in the polls to Senator Casey.
