Californians, it seems, are paying very high prices for gasoline -- an average of $4.668 a gallon, the highest price in the nation, to be exact. But why? Well, that's what Senator Dianne Feinstein wants to know. If fact, she's called for a federal investigation into gas prices "because she doesn't think they are related to supply and demand."

According to AP, "Feinstein says that paying hundreds of dollars every time you fill your tank is unthinkable. For the second time in the last few months, the California Democrat has sent a letter to the Federal Trade Commission asking for an immediate probe." In her letter to the FTC, Feinstein wrote that "[p]ublically available data appears to confirm that market fundamentals are not to blame for rising gas prices in California."

According to GasBuddy.com, via HuffPo, "[a] station in Long Beach south of Los Angeles had California's priciest gas at $6.65 for a gallon of regular." Gas prices are expected to climb higher before they dip ever so slightly.
