Democrats in the late Rep. John Murtha's (D-Pa.) district will recommend a candidate on March 6 for the special election to replace him.

The "recommendation convention" will be held at 10 a.m. in Delmont, Pa. The decision will be non-binding, with the final say resting in the hands of the state executive committee on March 8.

Counties in the district will have weighted votes, depending on their share of voters in the 12th district, with the big counties being Cambria, Fayette, Washington and Westmoreland.

Republicans will pick their nominee on March 11. In their case, the local counties will have the final say.
