Rubio said "out-of-control politicians" in Washington had put the future at risk.
"Like most Americans, Floridians are frustrated with arrogance in Washington," Rubio said Saturday. "They have had enough of the failed stimulus, of record deficits, of reckless spending, and of economic policies that are killing jobs."
Rubio, a product of Florida's politically potent Cuban exile community, is running against Democrat Kendrick Meek and Gov. Charlie Christ, who is campaigning as an independent. The Hill described Rubio Saturday as having the backing of the Tea Party crowd.
Rubio, former speaker of the Florida House, said his immigrant parents toiled at blue-collar jobs to provide opportunities for their children.
"Will we remain that type of country? Well that depends on the decisions we make right now," Rubio said.
