Think of this as having all of the names in one place, since you've likely heard it: Joe Allbaugh joined Rick Perry's presidential campaign as a senior advisor, apparently sitting at the top of the organization chart. Nobody is leaving the campaign, apparently, though the roles of the new folks and the pre-existing folks aren't entirely clear. Allbaugh, until now a lobbyist, managed George W. Bush's campaigns for governor in 1994 and for president in 2000 and Rudy Giuliani's campaign for president in 2008.
They've added Tony Fabrizio and Fred Maas as senior advisors too, and Curt Anderson, Jim Innocenzi and Nelson Warfield will work on the media squad for the campaign. And Stanton Anderson will be the campaign's liaison to Congress.
