That things are getting nasty between Ted Cruz and Donald Trump right now is not an accident. As Margaret Hartmann at New York magazine noted Monday morning, “Now, after a few days of soul searching and passive-aggressive sniping, the Trump-Cruz bromance is officially over.” Cruz, who has spent most of the campaign with his nose firmly embedded in Trump’s rear has done an about-face. This is almost surely by design. Cruz has been drafting Trump for months now, using Trump’s ability to rally the right wing nuts that Cruz needs to win, and now that the primaries are getting closer, he’s going to try to pull out and pass Trump. But it seems Cruz may not have learned the most important lesson: If you’re going to come at the king, you best not miss.

Ted Cruz unleashes his attacks on Donald Trump, but Trump may be impervious to the “inauthenticity” charge
