I’m not exactly surprised, but the U.S. Chamber of Commerce is endorsing Marco Rubio in Florida’s Senate race.

“We will endorse Marco Rubio because he has a record of standing up for the people of Florida during challenging economic times,” said Bill Miller, the U.S. Chamber’s senior vice president and political director who will attend the event with Rubio. “He is an invaluable leader who has a common sense approach to job creation and getting America back on the road to recovery.”

“On issues ranging from competition in the health care industry, to lowering taxes, to reducing energy costs, Florida’s businesses and workers will have a tireless advocate in Marco Rubio,” Miller said.

In total, the U.S. Chamber of Commerce, the National Federation of Independent Business, the Associated Builders & Contractors, the Associated Industries of Florida and the Club for Growth have all endorsed Rubio as the only candidate who will be a check-and-balance against the anti-jobs policies coming out of Washington and offer a clear alternative.
