When former speaker of Florida's house of representatives Marco Rubio (R) formed a Senate exploratory committee in the beginning of March, he told Politico that he would run for governor if Republican Gov. Charlie Crist sought the U.S. Senate seat. But, as of April 3, Rubio had changed his tune, telling Politico his decision was no longer dependent on what others will do. Last night, while speaking to a group of College Republicans and Students for a Free Cuba at George Washington University, Rubio affirmed that his decision to run for the Senate has "nothing to do with other people that are planning on running." When asked after the event if he would run for governor if Crist runs for Senate, Rubio replied: "I'm focused on the U.S. Senate opportunity largely because this is such an important moment in American history. I think the Senate's going to be the intersection of all the major issues confronting our country for years to come, so I'm focused on that and I'll make a permanent decision very soon." Asked if he could say whether "very soon" means within a specific time frame, Rubio replied that he didn't have a "time frame in terms of days and hours, but we're pretty much in the final stages of our exploratory phase, so we'll be having announcements coming shortly." "Who is running in the [primary] race is irrelevant to me," he said. "What's relevant to me is whether I think I can be an effective spokesman for what I believe in at a key moment in American history."
