Anyone linking Keystone pipeline to current oil prices just shows they're a partisan rube that knows nothing about the energy industry.
The extension wouldn't have added one drop of oil to 2021 supply, and Keystone already has a pipeline going to the gulf for exports of Canadian oil, the extension would have just been a more direct route than their current pipeline. Look at the proposed extension in Keystone's own map and tell me what this would have done for US oil production?
