Connie Mack IV

Buffeted by accusations of laziness by Bill Nelson's campaign, Rep. Connie Mack IV is out with a new ad today that unleashes his most potent weapon: his name.

The ad ties the younger Mack directly to his popular father, former Senator Connie Mack III.

And he does it through the testimony of his mother, Priscilla Mack.

Just like the temperature of a fever stricken patient, Medicare is on the rise as the hottest campaign issue in Florida ever since Paul Ryan was named as Mitt Romney’s running mate.

Senate candidate Connie Mack IV made a campaign swing through Pinellas and Sarasota counties today.  But while he tried to focus on the November election, questions about Mack's past keep resurfacing.

One of Connie Mack's stops today was at Sayler's Suncoast Water supply store in Pinellas Park. It was part of his campaign to focus on how he would help small businesses that are beset by what he calls a crush of government regulation.

In an interview with WUSF, former Sen. George LeMieux is standing behind his decision to attack Rep. Connie Mack as the Charlie Sheen of Florida politics.

The Republican Senate primary campaign in Florida has heated up fast, after information about Connie Mack IV's legal troubles -- including fistfights and financial woes -- was published in the Tampa Bay Times and Miami Herald.

Now, LeMieux's campiagn is using that information in "Two and a Half Macks" -- an animated ad on the internet.
