Republican Westchester County Executive Rob Astorino compared Gov. Andrew Cuomo’s agenda to children’s candy: Fun to eat, but could cause cavities.

“Last night I took the kids to the diner and they give away lollipops at the end when you pay,” he told reporters at an annual gathering of the Conservative Party in Albany. “Kids want a lollipop because they’re free and they taste good. It doesn’t mean they’re good for their teeth.”

A Siena College poll released this morning found there was broad support for most of Cuomo’s major agenda in the new year, including an extension of the state’s surcharge on millions, reduced tuition costs for SUNY students whose families earn $125,000 a year and less and a $2 billion clean water infrastructure fund.

Most of the measures have majority support and the backing of Republican voters, including the millionaires’ tax extension.

But Astorino cautioned there needs to be a thorough review of the governor’s agenda needs to be conducted.

“This state is rotting. It’s rotting because we can’t afford what we already do,” he said. “Nobody thinks that free is free and somebody has to pay.”

Astorino is considering a second run for governor next year as Cuomo seeks a third term.
