After a bruising contest that saw negative attack ads and arguments about contributions from political action committees, state Sen. Andy Harris defeated nine-term incumbent Rep. Wayne Gilchrest  and state Sen. E.J. Pipkin in the Feb. 12 GOP primary in Maryland's 1st Congressional District.

Since that time, Gilchrest has been highly critical of Harris, leading many to believe that he may endorse the Democratic candidate, Frank Kratovil. His longtime aide, Lynn Caligiuri, joined the Kratovil campaign in April as a finance coordinator. Harris picked-up Pipkin's endorsement.

Despite the divisions between the incumbent congressman and the party's nominee, Harris Campaign Manager Chris Meekins told PolitickerMD.com today that Republicans are "unified behind Andy Harris."
