Congressman Dan Maffei of upstate New York, a Democrat, is also seeking the Working Families Party nomination, so he filed a petition to be on the Working Families Party primary ballot. That petition has been challenged on the grounds that the circulator, Kane Miller, is not truly a New York state resident. See this story. Miller is registered to vote in New York state and is enrolled in the Working Families Party, but the challenger will attempt to show that he is really domiciled in Georgia.
Although the challenge probably won’t reach the constitutional issue of New York’s ban on out-of-state circulators, it might. Bans on out-of-state circulators have been invalidated by courts in Arizona, Illinois, Kansas, Nebraska, Ohio, Oklahoma, Virginia, and Wisconsin. Also, California, Michigan, and D.C. repealed their bans after they were sued. Both Arizona and Virginia tried to persuade the U.S. Supreme Court to hear their appeals on that issue, but the U.S. Supreme Court turned down both states.
