A Las Vegas billionaire who has said he could dump as much as $100 million into the 2012 elections has donated $1 million
of that chump change to a super PAC backing Republican Rep. Connie Mack in his race for U.S. Senate, according to the Tampa Bay Times
Mack, despite facing an August primary against
, Mike McCalister, and Dave Weldon, declined a debate invitation earlier this month
because, as a spokesman put it, "It's clear the race for the U.S. Senate in Florida is now between Connie Mack, the Republican, and Bill Nelson, the Democrat."
He's also attracted high-profile endorsements from Jeb Bush, Mitt Romney, and Sen. Rand Paul. A poll from the end of May showed Mack with a considerable advantage over his primary opponents, but also that Mack and LeMieux were both close to Nelson
