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."
