(CNN) - Mitt Romney is running well ahead of his rivals in New York, according to a survey released Wednesday.
The poll from the Siena College Research Institute showed Romney besting his closest competitor Rick Santorum by 15 percentage points. Romney, the former governor of Massachusetts, had the backing of 38% of likely GOP voters in New York, compared to 23% who support former Pennsylvania senator Santorum.

Two other White House hopefuls, former House Speaker Newt Gingrich and Texas Rep. Ron Paul, trailed the two leaders by double digits. Thirteen percent of New York Republicans backed Gingrich and 11% supported Paul.
The Siena poll was conducted February 26-29, ahead of voting on Super Tuesday. The poll surveyed New Yorkers before and after voting contests in Arizona and Michigan, which took place February 28.
Romney's lead in New York is hardly surprising – the GOP hopeful has thus far won every state in the Northeast, including New Hampshire's first-in-the-nation primary on January 10, Maine's GOP caucuses on February 11, and contests in Vermont and Massachusetts on Super Tuesday. New Yorkers go to the polls April 24.
In terms of favorability, Siena's poll offered Romney both good and bad news. While his rating rose among registered Republicans from 52% to 57% since the poll was last taken in early February, his rating among all registered voters dropped from 35% to 32%.
Romney's favorability among both groups was the highest of any of the four major GOP candidates.
"Each of the four Republican presidential contenders is viewed unfavorably by a majority of all New York voters," Siena pollster Steven Greenberg said. "Even among just Republican voters, only Romney has a majority viewing him favorably, while Paul and Gingrich have more Republicans viewing them unfavorably than favorably."
Pitted against President Barack Obama, all four candidates struggled by large margins. Romney fared the best, but stood 26 points behind the incumbent Democrat, taking 34% to Obama's 60%.
"While there are still eight months until Election Day and the race will certainly crystallize once the Republicans select their nominee, at this point it does not appear that the Democrats' run of six consecutive presidential victories in New York is in danger of being snapped," Greenberg said.
The Siena survey was conducted by telephone from 808 registered voters in New York. The sampling error was plus or minus 3.4 percentage points. For the GOP horserace, 230 registered Republicans were surveyed and the results carried a sampling error of plus or minus 6.5 percentage points.
