Zero is the number of delegates the establishment’s Marco Rubio pulled from the Michigan and Mississippi primaries.
The American Conservative’s Daniel Larison calls Rubio’s campaign finished. Rubio had been counting on a victory in his winner-take-all home state of Florida. He has been steadily behind Trump in Florida, and even before last night’s Michigan/Mississippi collapse had in recent days been losing momentum. Now with a zero delegate haul in Michigan and Mississippi, it appears that Rubio will lose additional momentum in Florida. The Rubio collapse is big news for Donald Trump who badly needs a win in Florida in order to gain a first ballot victory at the Republican convention.
