U.S. Sen. Marco Rubio, R-Fla., a possible candidate for the Republican presidential nomination in 2016, continues to remain active in Iowa, home of the first presidential primary. From his perch at Reclaim America PAC, over the weekend, Rubio called on supporters to support Iowa state Sen. Joni Ernst who is running for an open U.S. Senate seat against U.S. Rep. Bruce Braley, D-Iowa.
