Your wrath is, in my humble opinion, misplaced. Carson made a statement to a reporter that, esentially, he was leaving Iowa, heading home and taking a break. CNN ran with it. The Cruz and Rubio campaigns also ran with it when they saw it on CNN.
Carson should really be saying, “I guess I could have been more clear about that.”
No, Cruz should have been more clear about it. A little phone call might have helped but then...it would have cleared it up, wouldn’t it?
