According to this story in the Palm Beach Post, the District Attorney of Palm Beach County, Florida, does not believe that any Florida law was broken by 17 voters who appear to have voted in both Florida and New York, in the November 2006 election.

The conclusion probably wouldn’t be any different if 2006 had been a presidential election year, either. Technically, someone voting for president in two different states in the same presidential election would not be voting “twice” for any office. This is because voters in November of presidential election years are not voting for president. They are voting for candidates for presidential elector. Of course, each state is conducting a separate election for that office. So, the voter would not be voting twice for any particular office.
