Conservative Democrat Hillary Clinton was heckled by environmentalists Thursday during a New Hampshire town hall event, and for good reason. The Los Angeles Times reports:

[T]he gathering grew contentious when a woman representing an environmental advocacy group pressed Clinton on whether she would support banning fossil fuel extraction on public lands, including the use of hydraulic fracturing, the controversial natural gas drilling technique commonly known as fracking.

Clinton had said in response to an initial yes-or-no question that she could not commit to such a ban until alternative sources of fuel were in place.
