Whatever
Cruz needs to get out in front of the palinization ASAP! Great if he hoisted them upon their own petards, as well: use a little Alinsky right away, mocking in advance any talking heads or journos who make the predicted comments.
I don't want to have to come up with all the ideas right now, but one general example for Cruz to say now: "Oh, the media loves to say I am doing this [whatever he is doing] for egotistical reasons. Did they say that about [a democrat whom they would NEVER call out]? Let me tell you how it will go. If I did run for President, you'd see media people come out and say X, then Y, then Z about me. Remember. I said this today, [early 2015]. They will accuse me of [aforementioned X, Y, and Z] as quick as anything, but they will never ask about my [important things he has done, relevant things]. And remember, when you see an interviewer or reporter hitting me with those accusations, how predictable it was! How biased they are, and indeed, how they lack even the most rudimentary curiosity or intellectual stamina. It's actually going to be quite funny, just watch."
