Texas has a unique law, requiring that any group that intends to petition for party status must notify the state no later than January 2 of an election year. This year, ten groups filed the notice, more than ever before. The requirement has existed since 1993, has never been tested in court, and would probably be held unconstitutional if a new party formed after January 2 ever challenged it in court.
The ten groups that filed the notice are described in this Politex story. The ten are Americans Elect, Christian, Constitution, Generation, Justice, Make America Great, Reform, Revive America, Socialist, and Texas Independent Party. The Christian and Generation Parties have recently said that they don’t really expect to petition in 2012, although because they filed the notice, they are legally free to do so.
