On May 28, the Illinois legislature passed HB 723, which makes it more difficult for qualified parties to nominate candidates after the primary is over. The old law let qualified parties nominate by committee meeting after the primary, if no one had run for that party in the primary. The bill says that candidates nominated after the primary must submit a petition with the same number of signatures that would have been needed if that candidate had sought a place on the primary ballot. The logic for such a petition is missing. The purpose of the petition to obtain a place on a primary ballot is to keep the primary ballot from being too crowded, but there is no rational reason for a petition for a candidate nominated at a party meeting. The party itself has already shown a modicum of support by having polled at least 5% of the vote in the preceding election.
This bill has no effect for political parties that are not ballot-qualified. The only parties that are currently qualified statewide in Illinois are the Democratic, Republican and Green Parties.
