LOUDONVILLE, N.Y. (AP) - A poll suggests New York voter sentiment has shifted from support of shale gas drilling to opposition by a narrow margin. The poll released Thursday by Siena Research Institute says 44 percent of voters surveyed opposed the Department of Environmental Conservation lifting a 4 ½-year-old ban on gas drilling using hydraulic fracturing, or "fracking," while 40 percent favored lifting the ban. Upstate voters opposed fracking, 51-38 percent. Last month, the Siena poll found voters statewide narrowly supported fracking, 42-36 percent. Siena pollster Steven Greenberg called the issue a "political land mine" for Gov. Andrew Cuomo, as neither supporters nor opponents have succeeded in getting a majority of voters to their position. The telephone poll conducted Jan. 10-15 surveyed 676 registered voters and has a margin of error of 3.8 percentage points. (Copyright 2013 The Associated Press. All rights reserved.
