The Strategic Petroleum Reserve is an old salt mine in Louisiana which currently holds under 600 million barrels of crude oil. It is intended for emergencies like supply interruptions like the Arab Oil Embargo of the 1970s. It is not intended to boost poll numbers.
The 30million barrels Biden is taking form the reserves to try to hold down gasoline prices that are hurting him at the polls would supply the country for about 2 1/2 days. There isn’t enough there to make up for Biden’s anti-energy policies. If he tries to fix the shortage his policies are creating with oil from the reserves, he doesn’t have enough to last until election day.
But when he’s used it all up, what happens if there is a real emergency?
