I have no idea what happened beyond the fact that a mainstream news source - CNN - posted that Carson was going to return to Florida for a few days after the voting.
What kind of idiot campaign announces this before the votes are cast? I believe most people who follow politics and heard that would believe he was headed home for good with a 4th place finish (as projected).
This is big smoke for a little fire.
Exactly, this all started with Carson himself because he was heading back to Florida.
