We are still months away from voters casting their ballots, but right now Governor Cuomo has a significant lead over his challengers, according to this month's Siena Research Institute poll. In a Democratic primary match up between Cuomo and actress Cynthia Nixon, 66 percent of voters are with Cuomo and only 19 percent with Nixon. Though, that number could change with her now officially running. The poll was conducted before she announced her campaign. And Cuomo leads both men vying for the Republican nomination, Senate Deputy Majority Leader John Defrancisco and Dutchess County Executive Marc Molinaro, by almost two to one.  The poll also shows a lot of support for several items on Cuomo's legislative agenda. Pollster Steve Greenberg breaks down the results.
