The people who did vote for Carson should be angry at him for taking at least three days off at a critical point of the campaign right before the New Hampshire primary.
Then the reason he gives for not campaigning for several days is he need to get a change of clothes! In a sense, Carson is cheating his supporters who voted for him or donated money to his campaign in good faith.
The only reason Trump is crying about this is because he's a sore loser. He can't discuss the issues in depth so he resorts to childish whining to distract the voters.
It's so clear, any idiot, even an Iowa voter, could see that.
It just had to be cheating, of some form. Carson blew it, big time. he just had to run to FLA to change his shorts. No sleeping on the bus trip to NH. Nope. No all night laundromat. Nope. When a candidate telegraphs the impression he's going home for clean socks, he's saying he's tired and not up to the rigors of campaigning. The politically astute saw that and ran with it. The Donald got bested in a deal. The art of the deal was played like a grade school class president campaign.
Pull up your panties, Donald.
