Sen. John Cornyn of Texas says tumbling gas prices have had the bad effect of making voters less interested in tackling the nation’s energy problems. True. But the Republican lawmaker from one of the reddest states in the union says the biggest stumbling block to energy security isn’t reliance on fossil fuels and an unwillingness by energy companies to invest in renewables. No, that would be too “simplistic.” Instead, Cornyn says its big government regulations that are preventing good capitalists from opening up more domestic energy production. And while he notes some of those new-fangled renewable sources like wind and biomass, Cornyn’s op-ed is really all about one thing — drill here, drill now, drill everywhere.
