A perennial candidate will compete against the Democratic and Republican nominees in the special election for the late Rep. John Murtha's (D-Pa.) seat.

Libertarian Demo Agoris's message of "less government, more freedom and less taxes" may siphon some votes away from Republican Tim Burns.

Agoris told the Johnstown Tribune-Democrat he is concerned about federal spending and would push for a balanced-budget amendment. "That's the reason I'm running," he said.

The special election is set for May 18.
