Newt Gingrich is attempting to revive his faltering campaign for president by attacking President Barack Obama’s energy policy. In a column in the conservative blog Human Events Wednesday, the former House speaker urged the approval of the Keystone XL pipeline project, the expansion of domestic oil and gas drilling, and the elimination of the Environmental Protection Agency, in order to help drive gas prices down to $2.50 per gallon. “The Obama administration’s ideological refusal to expand American energy production continues to block the development of resources which could lower gasoline prices dramatically,” Gingrich wrote. “As we saw most recently with the administration’s rejection of the Keystone XL pipeline, the president is more interested in playing favorites with environmental extremists rather than embracing the ‘all-of-the-above’ strategy that could achieve energy independence and help all Americans now.”
