It looks like the Republican field against Florida Sen. Bill Nelson (D) in 2012 is growing.
Rep. Connie Mack (R-Fla.) is the latest to enter the fray. Mack took the fight to Nelson in a Orlando Sentinel op-ed on Wednesday -- a clear sign that he is angling for a Senate run.
Mack called on Nelson to support extending the Bush tax cuts.
"Admitting he was wrong to oppose the Bush tax cuts in 2001 and 2003 would be a first step for U.S. Sen. Bill Nelson to signal he 'got the message' in the recent citizen revolt," Mack wrote, referring to the 2010 election results in which Republicans made large gains in Florida. "Nelson has an opportunity to make amends and lead the charge for Senate Democrats to extend the Bush-era tax cuts in the lame-duck session of Congress."
Mack hasn't hidden his Senate aspirations but will likely face a contested GOP primary in 2012 if he runs. Outgoing appointed Sen. George LeMieux (R) has already said he is mulling a challenge to Nelson.
