YONKERS - A new poll shows Gov. Andrew Cuomo still leading Rob Astorino in the race for New York governor, but it's the third straight month that Cuomo's numbers have slipped with New York voters.

The Siena College poll has Cuomo leading the race with 58 percent compared to Westchester County Executive Rob Astorino's 28 percent.

Just last month, the poll had Cuomo leading with 61 percent to Astorino's 26 percent.

The telephone survey of 772 registered New York voters was conducted just last week.

The poll also reveals that Astorino remains largely unknown, with 66 percent of polled voters either not knowing who he is or having no opinion.
