Nothing to do with Obama, of course.

(The Hill) — Oil speculators, not a lack of domestic drilling, are to blame for the nation’s rising gas prices, the top House Democrat argued Wednesday.

House Minority Leader Nancy Pelosi said unscrupulous Wall Street investors have artificially inflated prices at the pump, which are climbing toward $4 per gallon.

The California Democrat called on Congress to take “strong action” to rein in the allegedly excessive speculation, and accused Republicans of protecting Wall Street profits at the expense of consumers.

“Wall Street profiteering, not oil shortages, is the cause of the price spike,” Pelosi said in a statement. “Unfortunately, Republicans have chosen to protect the interests of Wall Street speculators and oil companies instead of the interests of working Americans by obstructing the agencies with the responsibility of enforcing consumer protection laws.”

The comments – arriving a day before President Obama is scheduled to address the issue of rising gas prices in Miami – represent just the latest shot in the perennial and largely partisan debate over the cause of price fluctuations in the oil and gasoline markets.
