He is not, and it is not doing the race any good to keep repeating it. Gingrich did that commercial to try to get republicans into the discussion because he knew that they could win it, but the republicans were being pretty much silent. Gingrich does not believe that the government should be pushing "green" for any reason. He has stated time and time again that the free market should dictate green energy. That is not a bad position.
Sorry, but he picked a funny way to show it.
