CHICAGO (AP) — A federal judge in Chicago has struck down as unconstitutional an Illinois law requiring any small political party to field a full slate of candidates in a district before any one of its candidates can get on the ballot. Judge Andrea Wood’s order Monday permanently bars Illinois from enforcing the law. The decision stems from a lawsuit filed by the Libertarian Party in Illinois. Plaintiffs’ attorney David Schoen says Wood is taking a stand against a nationwide tendency of established parties to erect barriers against small ones. County election districts typically have the most seats up for election, from clerks to coroners. Finding a candidate for each has been hard for small parties. With the law Illinois struck down, more parties should appear on county ballots in November’s general election.
