Long before Texas Gov. Rick Perry officially launched his presidential bid last weekend, we learned that some of former president George W. Bush's longtime supporters aren't too fond of him.

What's their beef?

Perry served as Bush's lieutenant governor in 1999 and 2000, after running as the GOP's candidate to replace Bush's retiring Democratic lieutenant governor in 1998. Former president George H.W. Bush campaigned for Perry during that race, but Perry's later criticisms of the younger Bush evidently angered some Bush-family supporters.
