The New York Working Families Party will nominate candidates in May, according to this story. For Governor, the party must decide whether to nominate incumbent Andrew Cuomo, or Cynthia Nixon. Those two candidates are also both seeking the Democratic nomination, but the Democratic primary is not until September.
If the WFP nominates Nixon, and the Reform party chooses someone besides the GOP candidate we could have a 5-way race with the greens and Libertarian Larry Sharpe.
