How many parties will be on the presidential ballot this year?
Which ones are they?
Are they the same as last elections?
Ballots are set by the state. It depends on which state you are in as to which parties have qualified for the ballot.
www.politics1.com has a list of all parties running candidates for President.
The following parties are on the ballot on my home state:
Republican
Democratic
Green
Libertarian
American Independent (state name of Constitutional Party)
Peace & Freedom (state party)
The Natural Law Party also has a slot, but they appear to be not running a candidate, as they have disbanded.
