But what I've got my eye on is Rubio's potential to come in second.
Bush, Kasich, and Carson should see the light and endorse Rubio. It's already too late, but come on! It's the only decent hope of stopping Trump.
UPDATE: Bush, appropriately, drops out.
UPDATE 2: He doesn't sound like he means what he's reading. When he says he's suspending his campaign there's a bit of a no from the crowd, but it's... I've got to say... Low energy.
UPDATE 3: "It's tough, it's nasty, it's mean, it's beautiful" -- running for President, according to Trump.
UPDATE4: Rubio says it's now, practically speaking, a 3-man race, and it's his campaign that has the best hope of bringing people together.
