On April 13, the Upstate Jobs Party, an unqualified party in New York state, filed a federal lawsuit against discriminatory New York state campaign finance laws. Those laws permit an individual to contribute more money to a qualified party than an unqualified party. The case is Upstate Jobs Party and Martin Babinec v Kosinski, n.d., 6:18cv-459. Here is the Complaint. Thanks to Joe Burns for this news.
The Constitution Party has a very similar case pending against a North Carolina law.
