The majority of New York voters say they are in support of giving municipalities the power to raise their own minimum wages.
According to the Siena College poll, 73 percent support letting cities raise the minimum wage on their own, without state approval.
That idea is strongly opposed by Governor Andrew Cuomo, who says it would create dangerous economic competition between cities.
Mayor de Blasio is in favor of it, saying it would enable him to address the unique challenges facing working families in the five boroughs.
Last year, the state legislature voted to raise the minimum wage statewide from $7.25 to $8 an hour.
The poll has a margin of error of plus or minus 3.5 percentage points.
