Tim Burns, a businessman who lost two elections to Democrat U.S Rep. Mark Critz last year, says he's running for the Republican nomination to oppose Democrat U.S. Sen. Bob Casey.
The 43-year-old Burns lost the general election to Critz in November, less than six months after losing a special election against Critz to fill the seat of veteran Democrat Congressman John Murtha, who died in February 2010. Critz had been a top aide to Murtha.
Burns joins seven other Republicans vying to run against Casey next year.
The others are John Vernon, a retired U.S. Army colonel from Tioga County; Harrisburg-area lawyer Marc Scaringi; Bucks County businessman David Christian; Laureen Cummings, a Scranton-area tea party activist; Bedford County pharmacist John Kensinger; Tom Smith, a former coal company founder from Armstrong County; and Chester County businessman Steve Welch.
