Baltimore County state Senator Andy Harris has filed to run for Congress again. Two years ago, Harris ran hard to the right and knocked off incumbent Wayne Gilchrest in a bitter primary contest. He later lost a general election that was so close, it took days before Democrat Frank Kratovil was declared the winner. Kratovil was set to announce his re-election campaign with events in Salisbury and Kent Island. Maryland’s first district encompasses all of the Eastern Shore, as well as parts of Harford, Baltimore, and Anne Arundel Counties.
