"With Republicans grappling with the fallout of an intra-party battle that may have cost them a House seat, the head of the Senate Republican campaign effort is making a pledge that may ease some of the anger being directed at the party establishment," ABC News reports.
Said Sen. John Cornyn: "We will not spend money in a contested primary."
However, Cornyn "said his pledge extends to races for open Senate seats -- not incumbents who may face primaries next year. The NRSC so far has endorsed candidates in four open Senate seats -- Florida, Missouri, Illinois, and Pennsylvania."
