Republican Senate candidate Marco Rubio set another fundraising record in the third quarter, raising some $5 million, according to his campaign.

The Republican ended the quarter with $5.5 million cash on hand for the home stretch of Florida's three-way Senate contest between Rubio, Gov. Charlie Crist (I) and Rep. Kendrick Meek (D-Fla.). 

"While we still fully expect this final report to show us trailing Crist in cash on hand, we are confident we will have the resources to meet or exceed whatever our opponents are spending on television during October," Rubio strategist Todd Harris said in a statement on the campaign's third quarter numbers. 

Crist and Meek have yet to release their third quarter fundraising numbers, but the independent is likely to have a cash on hand edge. Crist reported $8.2 million in the bank at the end of the second quarter.  

Overall in the second quarter, Rubio easily outpaced his opponents in fundraising with his $4.5 million haul. Crist raised $1.8 million and Meek raised just over $1 million. 

The latest polling in the race show Rubio pulling away. The latest Quinnipiac poll had Rubio up 13 percentage points.
