You might say, "Who else was he going to endorse?" But still...

Florida's Republican party chairman endorses Senator McCain.
Here is part of the statement just emailed to me:

Chairman Greer also announced that Florida’s Republican National Committeeman and Committeewoman, Paul Senft and Sharon Day, are endorsing Senator McCain, securing Florida’s three Republican National Committee members for McCain.
