On February 3, Rick Jackson held a press conference at his company’s Italian-inspired Roman Colosseum headquarters in Alpharetta to announce his decision to run for governor of Georgia. The healthcare staffing entrepreneur, who is running as an outsider who will cut taxes, crack down on criminal illegal immigrants and fix the health care system, has no experience in politics. What he does have are survival instincts, a rags-to-riches story and a fortune to spend.

Most polls show Jones prevailing by a couple points over Jackson; the winner will face former Atlanta Mayor Keisha Lance Bottoms in November.
