Even a little-known, rookie candidate who has to explain how he led a company fined $1.7 million for Medicare and Medicaid fraud has to be taken very seriously when he's on track to spend more than $25 million in the primary.
It's interesting to contrast the McCollum campaign response to Scott -- publicly ignore him -- with the Kendrick Meek Senate campaign, which immediately started publicly hitting billionaire primary rival Jeff Greene over his controversial business background.
UPDATE: The McCollum campaign responds: "Bill McCollum enjoys broad support from Floridians across the state and is running on his strong record of leadership and experience. He is the one candidate in this race equipped to tackle Florida’s serious economic challenges. He recently rolled out an economic agenda that will create 500,000 jobs in six years. Rick Scott is a relatively unknown candidate that will have to answer some very serious questions about his history if he is to be viewed as a credible candidate."
