U.S. Rep. Tom Allen has refused to two debates with primary challenger Tom Ledue.
Allen and Ledue are both running for the Democratic nomination for U.S. Senate. The winner will challenge U.S. Sen. Susan Collins in November.
Allen, the well-known candidate, has been campaigning since last year. Ledue, the long shot candidate, jumped in the race in January.
Ledue said he is running to encourage conversations that Allen wasn’t bringing up.
