There is no shortage of available crude oil, domestic or imported, in the
United States, and for the last few years there has been a glut at the nationâ(TM)s
largest crude oil terminal in Cushing, Oklahoma. Canadian tar sands oil
would be processed for greater use in the U.S. only as other imported or domestic
sources are reduced. Replacing Mexican oil with Canadian oil would
only trade the closer source for the more distant.
