You can say the exact same thing about Cruz and Rubio.
If Cruz and Rubio want to run for president, they are responsible to run a strong campaign and not stumble into situations like this.
This exists, because they made it exist. They did it.
Whatever happens or does not happen as a result of their choice of action is on them.
Fair enough, but right now... it is not Cruz or Rubio doing the cry baby routine... it is Carson and some posters in this thread.
