Marco Rubio, Florida’s leading GOP U.S. Senate candidate, raised over $4.5 million during the second quarter of 2010. Rubio has now hauled in over $11 million in total. “A year ago, many were convinced that a principled campaign against the big spending Obama-Pelosi-Crist-Meek agenda stood no chance in the face of better-funded and more popular opponents,” Rubio said in the statement. “A year later, I’m thankful that our supporters have always understood what the stakes are in this election and have rallied behind us to create this movement.” Gov. Charlie Crist, Rubio’s independent opponent, has to announce his numbers for the quarter by the end of this week.
