In another sign that he's likely running for president, Mississippi Gov. Haley Barbour has hired Jim Dyke to work as a communications adviser on his political action committee.
The hiring of well-regarded staffers is typically seen as a sign that a prospective candidate intends to run, because the assumption is that top talent won't join a team unless he or she has received private assurances that the candidate is likely to run.
Dyke has worn a number of hats over the years. In the 2004 election, he ran the communications department at the Republican National Committee and in 2008 he worked for Rudy Giuliani.
