Ted Cruz once proudly wore a belt buckle reading “President of the United States” borrowed from George H.W. Bush. He campaigned and worked for, and helped write a book lavishing praise on, that former president’s son, Dubya. And the endorsement of George P. Bush, the family’s latest rising political star, lent credibility to Cruz’s then little-known 2012 Senate campaign. (AP Photo/Barry Thumma, File)
