The request being made by congressional democrats is to release 60 million barrels of the SPR, out of about 600+ million barrels. Sound like a lot, until you realize the USA's consumption is 20 million barrels a day. So you're talking about a 3 day supply for the nation. This would have no effect on oil prices. The Administration's best bet would be to announce that they would temporarily cease buying for the reserve (but leave it as is), and request Congress temporarily drop the per-gallon tax on gas by 5 cents. They should also move again to authorize drilling in that untapped oil field in Alaska. This would put Kerry and the democrats on the defensive; they would have to either cede a domestic issue victory to the President by agreeing to either or both, or be seen as an impedement to a solution.
BTW, Kerry voted against the temporary fuel tax decrease idea when Clinton was faced with the same issue. And yes, he also supported the move to raise fuel taxes by 50 cents per gallon once before. Odd positions from a man who owns so many SUVs (you know, the ones he says he doesn't own when addressing enviromentalists).
Interestingly, the same democratic voices that are demanding the release of oil from the SPR are the ones against drilling in Alaska, even though it would have a greater and more lasting affect on reducing our dependence on foreign oil than the inconsequential release of 3 days oil from the SPR.
