He called McConnell a liar three times. Ouch. Things may get a bit frosty in the Senate cloakroom and the Capitol Hill Club. Cruz is desperate to generate some publicity to get his presidential numbers up and compete with Trump. Bashing Boehner and McConnell is a brilliant ploy. You won't hear this from say, John Kasich or Jeb Bush.
Finally, we may possibly have a guy who is willing to do whatever it takes to win. Whose goal is not to lose gracefully. Actually we may have two such guys, Trump and Cruz. Could be a heck of a ticket.
