ALBANY, N.Y. (AP) — Political challengers to New York Gov. Andrew Cuomo are making pilgrimages to Pennsylvania drilling sites to argue for and against hydraulic fracturing for natural gas — and highlight Cuomo’s reluctance to weigh in on a subject that almost evenly divides voters.

Green Party candidate Howie Hawkins opposes the drilling technique, also called fracking, and last week visited sites in Pennsylvania to highlight what he says are negative health and environmental impacts.
