When it comes to imported oil, where should the U.S. be doing its business? Well a new poll of nearly 2,500 Americans indicates overwhelming support for Canada as our most secure, reliable, and environmentally responsible oil supplier. The poll, conducted by Anderson Insight, reveals 74% see Canada as our best choice based on the “economic interests of America,” compared to only 14% for Mexico and 9% for Saudi Arabia.  More than 80% support more use of Canadian oil, and an astounding 72% believe the U.S. should approve the Keystone XL pipeline as soon as possible, including a strong majority of Democratic Party supporters.
