So, what's the state of play on energy in the presidential race? I'm glad you asked.
Broadly, what's happened is that both parties now perceive, accurately, that the public is pro-energy. That's why both parties are grappling for the "all of the above" slogan.
"Pro-energy," in the U.S. public's case, means pro more energy, cheaper energy, cleaner energy, and more secure energy. What the public does not like is the trade-offs between those goals. It doesn't like hearing that it has to give anything up. It doesn't like hearing about "anti-energy" penalties and prohibitions. And it never likes favoritism, waste, fraud, or generic "spending."
Given that all energy policies involve trade-offs between various desiderata, a political party's ability to sell an energy policy to the public hinges on its ability to evoke the right frames. More/cheaper/cleaner/safer energy always polls well. Restraints, added cost, pollution, and foreign-ness (especially Middle Eastern-ness) do not.
This basic dynamic helps explain why Mitt Romney is not dropping Solyndra. Conservatives still see it as one of their bests attacks on Obama. It evokes Big Government spending, cronyism, waste, and failure (i.e., less energy). It tars the rest of Obama's clean-energy programs, nay his entire agenda, by association.
