According to the statute, Foley can be replaced with a new GOP candidate, however, since the primary has already been certified Foley's name must stay on the ballot but all his votes goes to the new candidate.
Section 4(a) is the relevent part

Florida Elections Law:
(4)(a) In the event that death, resignation, withdrawal, removal, or any other cause or event should cause a party to have a vacancy in nomination which leaves no candidate for an office from such party, the Department of State shall notify the chair of the appropriate state, district, or county political party executive committee of such party; and, within 5 days, the chair shall call a meeting of his or her executive committee to consider designation of a nominee to fill the vacancy. The name of any person so designated shall be submitted to the Department of State within 7 days after notice to the chair in order that the person designated may have his or her name on the ballot of the ensuing general election. If the name of the new nominee is submitted after the certification of results of the preceding primary election, however, the ballots shall not be changed and the former party nominee's name will appear on the ballot. Any ballots cast for the former party nominee will be counted for the person designated by the political party to replace the former party nominee.
Well, well, well...then Major Garrett was wrong...OR, I heard him wrong (which is entirely possible).
I am SURE by Brit's show tonight it will all be researched at Fox...
Thanks for the link.
