With the campaign speeches out of the way, and the rush to the polls subsiding, Ken Hoagland, communications director with the supporters of the Fair Tax, said, "No matter who wins today, the fair tax won."

Six out of the eight GOP candidates have mentioned or supported the idea of the Fair Tax, Hoagland said, which calls for an elevated national sales tax and elimination of the federal income tax.

The fair tax proposal also grants a "prebate" to taxpayers on necessities like food up to the federal poverty level.
