Judging from his many campaign e-mails, Sen. Pat Roberts, R-Kan., wants to line up endorsements from all 790,000 registered Republicans in Kansas as he runs for a fourth term next year. And the senior senator had nearly $1.5 million as of June to spend shoring up his already strong popularity. So Leawood radiologist Milton Wolf (in photo), the distant cousin of President Obama who announced his primary challenge Tuesday, has some heavy lifting to do to persuade Kansans that Roberts is not conservative enough and that "not even Moses himself should be in Congress for four decades." And the Club for Growth, the Senate Conservatives Fund and the Madison Project aren't ready to commit to helping Wolf, according to National Review. "We'll be keeping a close eye on this race to see if the grassroots conservatives in the state mobilize behind Dr. Wolf," Daniel Horowitz, the Madison Project's policy director, told National Review.
