The title is from Washington Post conservative columnist Jennifer Rubin yesterday, who took freshman Senator Ted Cruz (R-TX) to task for mocking his fellow Republican senators in public over the weekend. Rubin's, and this morning Joe Scarborough's admonishments notwithstanding, it's hard to see Ted Cruz doing anything other than what he has been doing since he got elected to the senate, which is basically being a royal pain in the ass for everyone else. Certainly calling other Republicans "squishes" won't endear him to anyone.

Here is part of what Rubin wrote:

There is being principled, and then there is being a jerk. Putting down your colleagues to boost your own street cred with the base falls into the latter category.
...
Cruz’s actions suggest an immaturity and lack of sophistication about conservative governance. He might want to apologize to his colleagues for betraying their confidence and sit down and think what it is he wants to do in the Senate. Obstruction is easy; governance is hard. And if the answer is that only hackneyed gestures (e.g. push for repealing Obamacare with a Dem Senate majority, but offer no alternative) that interest him, then the people of Texas are being shortchanged. Worse, he’s doing nothing to suggest he’s a man of stature and future leader in the party.
