"The Democratic presidential candidates who promise to ban fracking are keeping a secret: The president can't do that.
At least five contenders for the Democratic nomination have called for a "fracking ban" in their plans for fighting climate change and shifting to renewable energy. The slogan appeals to the party's most left-leaning voters.
But banning hydraulic fracturing would take an act of Congress. And getting Congress to do it would be difficult, even if the Democrats control both chambers.
The oil and gas industry, though, shouldn't take much comfort from that, energy analyst Kevin Book says. There are still a lot of ways for a president to affect the industry unilaterally."
