Many have been blaming President Obama for the rise in gas prices. Analysts are predicting that gas prices will be dropping over the summer. Will those blaming Obama for a rise in gas prices praise him for lowering gas prices? I doubt that they will. Is Obama responsible for the rise or fall of gas prices? The President is only one of many actors in events with many causes.
