The Maryland Green Party has 13 candidates on the ballot this year for Maryland legislature. That is the most such candidates the party has ever run. Maryland only has legislative elections in midterm years. In 2002, the party had three candidates for the legislature; in 2006 it had eight; in 2010 it did not have any; in 2014 it had one.
The only other minor party on the ballot in Maryland, the Libertarian Party, has five legislative candidates this year.
Although the Constitution Party is ballot-qualified in South Dakota, it has no nominees on the November 2018 ballot because it has two factions, each of which chose its own nominees in separate conventions. After a state court refused to adjudicate the internal dispute, one faction went to federal court, and the other faction intervened. But for many procedural reasons, the federal court also declined relief. Here is the opinion in Johnson and Hubbel v Krebs, 4:18cv-4108, issued October 1. The case had been filed on August 29.

The state committee of the Working Families Party of New York will decide tonight whom to nominate for Governor. See this New York Times story, which has quotes from many party leaders on both sides of the issue/
Virginia election law lets parties decide whether to nominate by primary or convention. But, the law also says if an incumbent is running for re-election, his or her wishes (as to how the party should nominate) override the wishes of the party. A unit of the Republican Party, the Sixth Congressional District Committee, won a lawsuit in U.S. District Court against this law. The state appealed to the Fourth Circuit. On September 27, the Republican Party filed this brief, arguing that the case should proceed and that the Fourth Circuit should affirm the U.S. District decision.
