On March 13, the Wyoming Democratic Party altered its upcoming presidential caucus, to entirely eliminate the in-person meetings, and rely entirely on the party-adminstered primary. See this story at Frontloading.
According to this story, New York Governor Andrew Cuomo has acknowledged the difficulty of petitioning due to the current virus situation. New York has its congressional and state office primaries in June, and candidates for district office in that primary must petition to get on the ballot. Only party members may sign these primary petitions, so it is customary in New York city and other urban areas in the state for petitioners to go door-to-door. The petitioning window has opened.
Also, the same story says State Senator James Skoufis has introduced a bill to move the presidential primary from late April to June. Petitioning for the presidential primary is not a problem, because it is over with, but the bill addresses concerns about holding an April election while the virus is a problem.
Thirty-four Democratic and Republican candidates have signed a petition to New York Governor Andrew Cuomo, asking that primary petitions be lowered or perhaps eliminated this year, due to health concerns. See this story.
At the March 3, 2020 primary, California’s 38th Assembly District had no incumbent running. Five Democrats and two Republicans filed. The two Republicans placed first and second, even though in the 2018 election, Democrats had won the seat.
The seat is in northern Los Angeles County.
The top-two system began in California in 2011. This is only the second time Democrats have been left without a candidate in the general election, in a district that the Democratic Party had won in the previous election. The first instance was in 2012, in the 31st U.S. House district.
Republicans suffered from this type of anomaly in 2018 in the 76th Assembly distrrict.
Virginia SB 126 did not pass, and the legislature has now adjourned. It would have repealed the law that lets incumbents dictate to their party which nomination method should be used for that particular office, convention or primary. The law was held unconstitutional last year by the Fourth Circuit, but it will remain on the books, even though it has no force.
