Read where Mike Murphy and the Yeb campaign were dropping $75 million to attempt to take out the whole field (probably Rubio before Florida), in order to make the race mano mano, between just TRUMP and Yeb.
They figure this scenario causes a coalesce of the anti-TRUMP forces, to try and hoist Yeb over the finish line.
I believe it is impossible this time. Not all of Trump’s support are base purists by a long shot. When you add in the Independents, moderates, and minority support and demographic advantages Trump has, they have their work cut out for them, in times of national security threats, where TRUMP blows out the field.
I don’t see how they take out everyone. If this is true about Rubio then he loses a bunch of his 12-15% but even if most of it goes to Jeb he’s still running third. This will come down to Trump and Cruz. The establishment pubbies have lost their party due to their own fault. They want same old same old and the same pockets lined and the same families enriched.
