Politico reports that the Young Guns Network, “a group affiliated with two former aides to House Majority Leader Eric Cantor,” just spent $104,628.00 to support six-term incumbent senator Richard Lugar in his primary battle to hold his seat against state treasurer Richard Mourdock. The money, according to disclosures, went to “mailers” in favor of the 80-year-old Lugar, who now looks likely to lose to his more conservative challenger.

“Young Guns … was designed to help leaders like Eric Cantor and Kevin McCarthy chart a new course for the center-right movement and the House majority,” Young Guns Action Fund super PAC founder John Murray has said. It’s not clear how this donation to Lugar furthers that cause. And it’s not clear why Young Guns is meddling in a GOP Senate primary. Indeed, Mike Pence, another young gun-type House member who’s now running for Indiana governor, has conspicuously failed to endorse Lugar for reelection.
