Gov. Andrew Cuomo continues to lead his Republican opponent Rob Astorino in the polls, with a Siena College survey released this morning showing him with a 29 point advantage.

But despite that lead, Cuomo’s favorable rating among voters in New York continues to ebb: 55 percent of voters have a favorable opinion of the incumbent Democrat, while 40 percent do not.

Cuomo in a Capitol Pressroom interview this morning placed the blame on the sagging numbers, in part, on the heightened politics of the campaign influencing voters’ opinions.

“I think we’re in the campaign season. There’s a natural gravitation towards a campaign season people become more political,” he said.

But he also pointed to uncertainty nationwide on the economy as well as security concerns, which he has placed a special emphasis on in recent weeks.

Voters, rightly or wrongly, assign blame to those in charge, Cuomo said.

“These are not good times,” Cuomo said. “The economy is still not great, there’s fear in terms of terrorism. So things are not good and the executive becomes a sort of barometer of the times. These are scary times, these are not good times.”

The lower numbers come after Cuomo and his running mate, former Rep. Kathy Hochul, survived a primary challenge from two little-known college professors, Zephyr Teachout and Tim Wu.

Cuomo’s re-election numbers remain high among self-identified liberals.

Asked about whether he’s shifting his tactics post-primary, Cuomo said he wouldn’t change his approach to public workers and teachers labor organizations.

“I knew what I was doing when I did not cater to the teachers union. I didn’t have to take the endorsement of the teachers union the first time, by the way.”

He also pointed to the low turnout as a reason to Teachout’s relative success.

“You have a primary in which 11 people voted, then you wind up with 60-40,” he said.
