BROOKLYN - A new poll shows support slightly declining for Gov. Andrew Cuomo.

According to the Sienna College poll, Cuomo is 30 points ahead of his only Republican challenger for office, Westchester County Executive Rob Astorino.

Fifty-eight percent of those surveyed support Cuomo, a Democrat, over Astorino. Only 28 percent of those polled are supporting the Conservative new-comer. Astorino announced he was running for governor last month, and has a lot of catching up to do when it comes to name recognition. Sixty-six percent of New Yorkers polled say they either don't know who he is or don't have an opinion about him.

The poll findings show a 3-point decrease for Gov. Cuomo since March.
