There's a part of me that still thinks Rubio will announce that he'll run for reelection to the Senate over the summer. It makes so much more sense for his future political career, and the pressure he's got to be getting from the NRSC (and from parts of the FL establishment too, who favor Bush and don't want to lose the Senate seat) must be intense.
I agree. But I still think Rubio will probably run for President, where his odds aren't really good. A Bush for President/Rubio for Senate campaign in Florida would be formidable.
