(CNN) - Add another name to the high profile Senate battle in Florida.
Republican Rep. Connie Mack has decided to make a bid, after passing on a run earlier this year for the GOP Senate nomination in the Sunshine State, a Republican source confirms to CNN.
Mack endorsed state Senate president Mike Haridopolos earlier in the race, but Haridopolos ended his bid over the summer. The four-term federal lawmaker represents Florida's 14th congressional district, in the Southwestern part of the state, but as the son of a former two-term U.S. senator with the same first name, Mack has statewide name recognition.
Former appointed Sen. George LeMieux, former state Rep. Adam Hasner and Col. Mike McCalister have all launched Senate campaigns.
The winner of next year's primary will face off against two-term Democratic Sen. Bill Nelson.
Two of the top handicappers, the non-partisan Cook and Rothenberg political reports, both consider the race competitive but give a slight advantage to the Democrats.
