In 2016, the New York Reform Party did not nominate anyone for President. For U.S. Senate, it only polled 17,680 votes. This showing suggests that the Reform Party won’t be able to poll as many as 50,000 votes for Governor in 2018. The party’s U.S. Senate candidate in 2016 was Wendy Long, who was also the Republican nominee and also the Conservative nominee.
Both them and the WEP were both even more of a satellite party than the Working Families’ Party is. It’s no wonder people aren’t voting for them, they probably see little point in doing so when they could just as easily vote for the respective main party.
