Rubio Lost Big. He Has No Realistic Path To Winning Before The GOP Convention.

Sen. Marco Rubio (R-Fla.), who was once called "THE REPUBLICAN SAVIOR" on the cover of Time magazine, lost big Tuesday night.

Rubio's been losing for a while. Even before Tuesday's results, Rubio had less than half of the delegates that the number-crunchers at FiveThirtyEight said he would need to be "on track" for the Republican nomination. But Tuesday night, when he lost badly in Michigan and Mississippi, made clear that he's a dead man walking.
