I dunno. Carson never struck me as being much of a schemer.
I think he just guilelessly told a reporter that he intended to stop off at home to rest and some clever rival teams noticed that the statement was ambiguous enough to be misleading. So they ran with it.
I was surprised to see Santorum endorse Rubio, I find Rubio to be especially devious and phony. If Carson endorses him as well that would also come as a surprise.
Carson also said he was going to Washington for the prayer breakfast after “changing clothes” in Florida.....
