Cruz did not just wake up Monday morning thinking, Hey I’m going to fire Rick Tyler today. When he took $10 million each from the Wilks brothers, Robert Mercer, et al he is beholden to some mighty powerful interests. When they say jump, he says “how high”.
I read that one of Cruz’ donors told him to stop attacking Rubio and to start going after Trump. The Cruz donors do indeed say jump and he says how hi!
