Romney: Obama Is ‘Biggest Impediment To Job Growth’ Because He Rejected Keystone XL | At last night’s CNN debate, former Massachusetts Gov. Mitt Romney blasted President Obama on the Keystone XL pipeline. In response to a question about creating jobs, Romney called Obama “the biggest impediment to job growth,” with his decision to reject the pipeline. “With regards to energy, because he has to bow to the most extreme members of the environmental movement, he turns down the Keystone pipeline, which would bring energy and jobs to America.” In reality, the entire environmental movement was joined by unions, farmers, and faith leaders in opposition to the tar sands boondoggle. The economically risky tar sands pipeline would actually export foreign oil to foreign markets, would increase the cost of Canadian oil imported to the United States, and wouldn’t strengthen the American economy.
