Speculation returns to Gov. Mark Sanford, regardless of his hold-out on endorsing McCain until after the primary season:

All the information I have suggests that McCain does not hold a grudge against Sanford. As a national Republican figure, Sanford has kept his profile low, but he has started to increase his visibility. He keynoted the Republican Party of Arkansas’s dinner last week; he is hosting the Republican Governors Association summer retreat this weekend in Charleston. He’s soon to speak to Republicans in Michigan. Last month, he attended the National Summit on Competitiveness in Chicago and spoke alongside two cabinet secretaries. And he joined Kathleen Sebelius at the Bilderberg Society meeting in Virginia two weeks ago.
