Sen. Kirsten Gillibrand remains in an extremely strong position to be elected to her first full term, according to a new survey.

A Siena College poll released today found that 51 percent of registered New York voters had a favorable opinion of the Democrat, while only 25 percent held an unfavorable opinion.

Gillibrand did even better when those surveyed were asked whether they would vote to re-elect her: 54 percent said yes, 28 percent said they would prefer someone else and 18 percent didn’t know.

But the 45-year-old Senator did best when matched up against her potential GOP opponents. In horse-race matchups, she bested Rep. Bob Turner, 65 percent to 24 percent, led Nassau County Comptroller George Maragos, 65 percent to 21 percent, and was ahead of attorney Wendy Long, 63 percent to 23 percent.

In the GOP primary, most Empire State Republicans didn’t know whom they were going to vote for. When GOP voters were asked about for whom they would vote in the primary, Turner pulled 19 percent, Long got 10 percent and Maragos received 5 percent. Sixty-six percent of registered GOP voters were undecided.

The survey was conducted from April 1-4 and polled 808 Empire State registered voters on landlines and cellphones by live telephone interview. The margin of error was 3.4 points for the full sample and 6.6 points among the questions that were just asked of the 218 Republican registered voters.
