Donald Trump marched through the Republican presidential primary field this year on the strength of a focused message: America used to be great. It isn't anymore. And that's mostly the fault of the Obama administration.
On Thursday, Trump applied that same thesis to American energy production. "America's incredible energy potential remains untapped," he told a North Dakota audience in what was billed as a major policy address. "It's totally self-inflicted. It's a wound, and it's a wound we have to heal."
