Among other topics, the Democratic candidates discussed fracking at yesterday's debate. According to Think Progress, their answers suggested different policies. Clinton said that she would support fracking under certain conditions:

Specifically, Clinton said that she would not support fracking when local communities don’t want it; when it causes pollution; and when fracking companies don’t disclose the chemicals they use.

“By the time we get through all of my conditions, I do not think there will be many places in America where fracking will continue to take place,” she said, adding that some places with fracking are not sufficiently regulated. “We have to regulate everything that is currently underway, and we have to have a system in place that prevents further fracking unless conditions like the ones that I just mentions are met.”

Sanders' answer was quicker:

“My answer is a lot shorter. No. I do not support fracking,” he said to applause.

The Republican candidates are all in favor of fracking. Here's what the AP reported Republican front-runner Donald Trump said on Friday:

GOP presidential front-runner Donald Trump says he thinks he can win New York, despite Democrats' significant voter registration advantage, because he's in favor of a practice called fracking. . . .

He points to Pennsylvania, which allows the natural gas extraction process, saying: "They took those beautiful, beautiful natural resources. They took 'em out."

He says that in Pennsylvania, people drive around in Cadillacs. He then pivoted to a Cadillac-sponsored event being held on one of his golf courses.

Cadillacs?
