Do the Democrats lose 50,000 votes every time the price of gasoline drops a penny? We'll have the answer to that question in a few weeks, but in the meantime cheaper gasoline raises some interesting questions.
The first of which is whether or not the Republicans have arranged to lower them to prevent what had seemed to be defeat in November. Certainly, the timing of the price drop might cause even the credulous to entertain a suspicion or two.
You may be sure that the Republicans are delighted to see gasoline fade from the list of voter irritations. You may also be sure that the Republicans would have arranged for prices at the pump to swoon if they could, but can they?
Not likely. To make the price of gasoline come down in Ohio, where the GOP is in big trouble, the prices have to drop everywhere. No special walled-off Ohio oil market, or even an American oil market, exists. If the price of oil is going to go down in Cincinnati, it is going to have to go down in Shanghai. Oil, as the economists say, is fungible.
There are times when energy prices are manipulated, California's electricity cost being an example. A few years ago, by closing certain generating plants and refusing to sell electricity from certain other plants, an artificial shortage was created, which drove up the price of electricity and drove ordinary Californians to the poorhouse.
But California is not part of a world electricity market. As opposed to oil prices, those electricity prices could be forced upward without worrying about how would-be suppliers in Canada or elsewhere would react. If California had been part of a world market, when the prices went up outside suppliers of electricity would have rushed in to sell and the prices would have been forced down again.
Because oil must be refined, it is possible to play some games with gasoline prices. Refineries can be pulled off line for no good reason except to drive the price of the products up. The operative word here is "up."
Driving prices down is another matter. Manipulators make money when the price goes up. Manipulators do not make money when the price goes down.
Down is going to cost somebody a lot of money. For practical purposes, the only way to make prices go down is to sell gasoline at a loss because you must sell it under the going price. Not quite the same as giving it away, but it's close.
And you have to sell a lot of it under the going rate. Last winter, for example, we saw President Bush's good friend the devil-defying Hugo Chávez , sell heating oil to poor Americans at lower-than-market prices, and guess what effect that had on the price of heating oil generally? None.
Last winter Chávez, through Citgo , owned by Venezuela, dumped 16 million gallons of heating oil at below-market prices in eight states, and if it pushed down the price of heating, nobody could see it. Imagine how many million barrels of oil it would take to depress the entire gasoline market--and how much it would cost. Rich Republicans, who are desperately clinging to every nickel out of fear the death tax will pauperize their heirs, are not about to make a campaign contribution of this magnitude. If that's the cost--and it would be--of keeping Denny Hastert in the House Speaker's chair, they'll take their chances  with Nancy Pelosi.
The Democrats, posing as the champions of the great unwashed as they do, dare not show their apprehension at the slump in gas prices even as they watch votes melt away. Nevertheless, every time gas prices drop, people kid themselves into believing the oil is going to flow forever and that we can go on living as we have forever.
If the past is any kind of a guide, the numbskulls in Detroit will postpone the design and production of truly energy-efficient automobiles, a decision that will ultimately put them out of business. Lower prices will bring research and development on more expensive alternatives to a halt. The thousands of undertakings, great and small, that can increase efficiency will be put off yet longer.
There will be no politicians of note who command national attention (Al Gore aside) to tell us that we are once more frittering away precious lead time between now and when (a) the oil runs out and (b) the environment crashes.
The American religion of every man for himself and the devil take the hindmost has made it a point of pride never to plan ahead, never to be ready and never to prepare. So in war after war we are caught with our pants down and in peace each Katrina is worse than the last one.
Whatever danger, no matter how real, how close or how certain, the response is, "Oh, the free market will take care of it" or "Aw, don't worry, technology has our back covered." So instead of throwing ourselves into energy conservation to postpone the day of disaster, we hear speeches about energy independence and ethanol.
As of now all ethanol can do is win the Midwestern farm vote. Yet the Democrats ought not to give up hope. The Republicans seem to have an inexhaustible supply of crooked pederast  Congressmen, and there is one deep truth, which is that oil prices, like all prices, fluctuate. Next time the Ds may catch 'em on the down cycle.
