One month ago, Americans were screaming about higher gasoline prices. Although there's still plenty to scream about these days, the panic at the pump isn't as pronounced now because prices are down eight cents from April 1. The reason for the drop-off isn't all that encouraging since it means the economy is slowing down a bit. Currently, the average price for a gallon of unleaded regular is $3.83 nationally, a drop of four cents from the previous week. Curiously, while gas prices are up 55 cents from the beginning of 2012, they're actually 13 cents less per gallon from this time last year. Republicans say the way to reduce costs is by opening up drilling, especially the Keystone XL Canada-to-Texas oil pipeline. Obama prefers an "all of the above" approach that includes giving regulators more power to go after speculators who artificially increase the cost of crude oil.
