A new campaign poll released to Poitico shows Republican senator Dick Lugar of Indiana five points behind his primary challenger, state treasurer Richard Mourdock. In the Wenzel Strategies poll, conducted on behalf of the Mourdock campaign, 44 percent of those Hoosier Republicans surveyed said they support Mourdock in the May 8 primary, with 39 percent supporting Lugar. Seventeen percent of those polled were undecided, suggesting that the final days of the race will be hard fought.

Another recent Mourdock-backed poll showed the candidate edging out Lugar, a six-term incumbent, 42 percent to 41 percent.
