Posey looks like a pretty solid conservative. Pro-life, Pro-2A, etc. The only folks who seem to be unhappy with him are Planned Parenthood and other left-wingers, and Free Republic Assistant Democrats who take every chance to bash Republicans.
Business as usual around here. Both Posey and Haridopolos appear to be pretty conservative. I wouldn't be surprised if this was a plan by Posey to prevent the party from shoving a RINO in through the primary, or damaging Haridopolos. As FL Senate President, he likely made some enemies.
