I think the mocking in the graphic was of Trump, not of Carson. I’m assuming here that you consider Carson a victim, not Trump.
No one should mock Carson, he is a thoroughly respectable man, but in my opinion the root cause of the entire fiasco is that he and his campaign were careless about the message coming from their campaign.
There is a good case to be made that the Cruz campaign should have sent out a “stand down” note when they knew Carson in fact was not withdrawing, and I think that is the basis of the Cruz apology. But none of this would have happened if Carson and his campaign had been attentive to their messaging.
Actually, I’m more bothered by the ‘voter error’ mailer than the Carson thing. And I don’t think Carson would even be in this race were he not black. He sounds anesthetized all the time, no?
