87% of the country is stupid and misinformed. All they see is gas price which means very little.
First off we don't burn saudi oil, we refine it into useable products. Sometimes in a global market saudi oil is cheaper to refine because of the type of oil. Gas refineries like lots of light sweet crude because of its low sulfur content. Heavier oils go to making things like plastics.
Second, it doesn't matter much in a global market. Any increase in supply should lower raw material costs. Gas refining is increasing, but US refineries are at near max capacity. Refineries aren't built overnight, they take years and are huge investments and refining is a very low profit oil industry activity. There are more profitable activities to invest in. Nobody wants a refinery in their neighborhood, just like they don't want a jail built near them.
