Thanks to the ACLU lawsuit settled against Iowa a few months ago, Iowa now has a procedure than an unqualified party can be listed on the voter registration form, if it placed a nominee on the ballot in the last election, and if it submits 850 signatures on a petition. The Iowa Green Party now has over 800 signatures on its voter registration petition, and the Iowa Libertarian Party now has 600. No other unqualified parties are attempting this.

Other states that have registration by party, but which refuse to tally the number of registrations for any unqualified party, are Arizona, Kansas, Nebraska, New Hampshire, North Carolina, Pennsylvania, West Virginia, and Wyoming. The policy of refusing to do a tally for any unqualified parties has been held unconstitutional in five states so far (Colorado, Oklahoma, Iowa, New Jersey, and New York).
