They've been trying to build one for years (Keystone XL) but have been stonewalled at every turn by Obama.
Not just Obama, but the by anti-oil people. They think by blocking the pipeline, they will be reducing CO2 in our atmosphere. The sad part is, they are actually INCREASING the amount of CO2 and other pollutants.
Don't forget that OPEC countries have been found financing anti-Keystone XL 'environmental' groups as a means to keep competition out of their oil markets and keep prices up. Then there's the railway owners, who would lose out if a pipeline was built. Much of the inland oil development is shipped by BSNF, a Berkshire-Hathaway company. Buffet is an Obama supporter who has publicly supported Keystone XL, but who knows what deals are going on behind closed doors? (my apologies if this is a repeat post, the last one didn't seem to take.)
