From Eric Dondero:

Karl Dickey at The Examiner reports:

Former state House Representative Adam Hasner has less to competition in his effort to gain entry to the U.S. Senate office currently held by Bill Nelson. Thanks to state Senate president Mike Haridopolos dropping out of the race for Florida's U.S. Senate seat, Hasner has one less heavily-favored Republican to go against to win the Republican primary, though he has nine others compete with - most notably George LeMieux who has been making the rounds.

Dickey, Chair of the Palm Beach County Libertarian Party and a 2008 attendee of the Republican Liberty Caucus convention in Orlando also notes:

No Libertarians have yet to file for the office and it seems doubtful former Libertarian Party U.S. Senate candidate Alex Snitker will run for the office in 2012.

Haridolopols was a guest speaker at that same 2008 RLC Convention, and serves on the RLC advisory board.

Hasner is a pro-defense libertarian, staunchly free market, and a vehement critic of radical Islam. A Jewish American, he is a friend and former State House colleague of Senator Marco Rubio.
