Romney claims the president has "doubled": gas prices. This statement is technically true, but should be qualified by the fact that prices were extraordinarily low when Obama took office.
Romney is attempting to hype up the Keystone XL, the pipeline project to transport oil from Canada to plants in the Gulf Coast. His point is that Obama botched a crucial energy project by wholly trashing the plans to import more oil from our neighbor to the north.
But what Obama really did was delay the assembly of the northern part of the new pipeline that was set through Nebraska's Sandhills, and he did so with bipartisan support from the state's lawmakers. A new, more environmentally sensitive route is set to be approved in a few months and the whole thing should be up by 2015.
