“I think we are going to crush them everywhere,” Mr. McConnell, the Senate Republican leader, said in an interview, referring to the network of activist organizations working against him and two Republican incumbents in Kansas and Mississippi while engaging in a handful of other contests. “I don’t think they are going to have a single nominee anywhere in the country.”
Elevating the nasty intramural brawl to a new level, Mr. McConnell on Friday began airing a radio ad in Kentucky that attacked both Matt Bevin, the businessman challenging him in the Republican primary, and the Senate Conservatives Fund, one of the groups trying to oust Mr. McConnell and a political action committee that has been a particular thorn in his side.
Mr. McConnell’s ad, his first singling out the Senate Conservatives Fund, raises a criticism that Speaker John A. Boehner and other Republicans have leveled at the activists — that they are fund-raising and business enterprises more than political operations. The ad refers to unnamed news media reports that assert that the PAC “solicits money under the guise of advocating for conservative principles but then spends it on a $1.4 million luxury townhouse with a wine cellar and hot tub in Washington, D.C.”
