I think we all fully realize that when the Republicans uniformly block each and every effort to deal with the rise in gasoline prices, then hold a pizza party on the floor of the recessed House in order to demand something be done about gasoline prices, they don't give a damn about gasoline prices. They apparently see it as another opportunity for a multibillion dollar giveaway to the oil companies, and an opportunity to rail that Obama and NASCAR are in the pocket of Big Tire Gauge, but that's about it.
But here's a thought. Since Congress is all about stimulus packages and tax breaks, let's give everyone a $200 rebate on tuning up their car. It'd stimulate the economy. It'll reduce gas consumption immediately, and significantly. A lot of people wouldn't otherwise do it, especially the people who tend to most need it. In other words, it'd work.
The only potential problem is that the Republicans don't give a crap about mechanics, since grease monkeys almost never plop down $28,500 donation checks like oil companies do -- so that's not really the kind of "stimulus" they care about. But hey, I bet it'd have a big impact on the parts market, so maybe they can beg at GM's trough afterwards. (And, cough, many of those parts factories are in swing states...)
Or, hell, we could just grind up some polar bears and call it a gas additive. I bet you'd find sixty votes for that.
