Clinton or Sanders would both beat every Republican candidate in a head-to-head contest in the general election, the poll showed. Sanders would beat all Republicans by 19 to 37 percentage points. Clinton would beat all Republicans by 7 to 25 percentage points, with Kasich giving her the toughest run.
Registered Democrats outnumber Republicans by a 2 to 1 margin in New York. No Republican presidential candidate has won the general election in New York since Ronald Reagan in 1984, and it isn't likely to happen this year, the poll showed.
The Siena poll of 800 New York voters was conducted Feb. 28 to March 3, and released six weeks before New York holds its presidential primary election, on April 19. It has a margin of error of plus or minus 4.1 percent.
