In this Jan. 18, 1999, file photo Texas Gov. George W. Bush, left, answers a question as Lt. Gov.-elect Rick Perry, right, listens during a news conference in Houston. With Perry running for president in 2012, the spotlight is shining on the tense relationship between the two Texans and their allied camps. The still-beating heart of the rift between them dates to Bush&#39;s refusal when governor to appoint Perry&#39;s brother-in-law to the Texas appeals court bench. In public, both Perry and Bush shrug off any friction. | AP Photo
