Florida will have twelve presidential candidates this year. By comparision, in 2000 there were ten; in 2004 there were eight; and in 2008 there were thirteen.
The twelve in 2008 are the nominees of the Democratic, Republican, Libertarian, Green, Constitution, Justice, Party for Socialism and Liberation, Peace & Freedom, America’s Independent, Socialist, Objectivist, and Reform Parties. These parties are listed in the order of how many states their presidential nominees are on the ballot (so far). UPDATE: an earlier version of this post said the Socialist Workers Party is on and that the Reform Party is not, but the post has been corrected.
Probably Florida will have more presidential candidates on its ballot than any other state except Colorado, although Louisiana might also have more but that is not yet determined. None of the other 47 states will have more than ten.
Four parties that placed presidential candidates on the ballot in Florida in 2008 did not do so in 2012. They are the Prohibition, Boston Tea, Socialist Workers, and Ecology Parties.
