More oil rigs doesn't mean cheaper gas.

Gas prices are of concern to everyone, especially  with an election coming up, and there are  lot of people who would have you think Obama isn't doing enough to help the U.S. oil industry and get those prices down.  Those same people want more pipelines, including the much discussed Keystone XL.  But actually foreign oil imports have fallen since Obama came into office, and, more importantly, studies show that more wells don't mean cheaper gas at all!
