The GOP establishment poured a lot of money, time and effort to ensure a Trump loss (he was not at his strongest in a caucus based system of voting) against Cruz in order to blunt Trump and try and have the Iowa loss derail Trump moving forward in NH. There Trump either loses or barely wins thanks to the post Iowa attacks and Rubio can be claimed as the comeback kid.
Cruz allowed himself to be used by the establishment for this purpose and they will now toss him to the curb.
Spot on with one correction. I see Ted IS the establishment. I know, it takes some mental gymnastics but he’s the insider pretending to be the outside to beat the real outsider, when he knows who the REAL insider is that they want and will get - Rubio. Sigh, this is exactly how we end up in the same place every damn time.
