Rep. Connie Mack, R-Fort Myers, left, debates U.S. Sen. Bill Nelson, D-Fla., on Wednesday, Oct. 17, 2012, at Nova Southeastern University in Davie, Fla. The campaign between Sen. Bill Nelson and U.S. Rep. Connie Mack seems to have fallen a bit flat. There are significantly fewer head-to-head debates between the candidates than there were in 2010, and the race is getting less attention nationally. To some degree the candidates seem to be duking it out in TV ads, similar to Gov. Rick Scott's 2010 strategy.
