There are two things wrong with your list of events. First of all, Cruz never said “Tell everyone Carson’s out and they have to vote for you!”. And second of all, not one voter has come forth and said “I was going to vote for Carson, but I voted for Cruz instead when I found out Carson was going back to Florida instead of campaigning in New Hampshire and South Carolina”. Not a single one.
“Not a single one.”
Not that WE know of.
