It's tempting to blame speculators for the price run-up. In March, U.S. Attorney General Eric Holder established a task force to investigate potential fraud in energy markets.
So far, it's "clear that there are lawful reasons for increases in gas prices, given supply and demand," Holder says in a statement.
It's also tempting to blame the falling value of the dollar for rising oil prices. After all, oil trades in dollars and since January the U.S. currency is down about 10 percent against the euro.
But Tom Kloza, chief oil analyst with the Oil Price Information Service, says it's more complicated than just that. Trouble in the Middle East is still spooking markets, and investors want to buy oil.
Not a single word about the drilling moratorium or lack of domestic drilling. Not a single mention that any hopes of domestic production are just ridiculous.
