"Ted Cruz is too often falling into the reflexive habit of voting no on everything and then mocking his colleagues."

Jennifer Rubin is "sorry to say."

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....

For starters, it’s just not smart to annoy colleagues whose cooperation and support you’ll need in the future. Second, as a conservative he should understand humility and grace are not incompatible with “standing on principle”; the absence of these qualities doesn’t make him more principled or more effective. Third, for a guy who lacks manners (see his condescending questioning of Sen. Dianne Feinstein (D-Calif.) he comes across as whiny. They yelled at me! Boo hoo, senator.

There is a deeper problem, I think, with Cruz’s approach to the Senate, which has nothing to do with ideology. The contrast between him and Sen. Rand Paul (R-Ky.) is telling. Paul is no less conservative than Cruz, but he is polite to a fault, soft spoken and gracious....

It's the old Mutt and Jeff routine! I like it.
