Clinton Gas-Tax Proposal Criticized

Joining in the criticism was House Majority Leader Steny H. Hoyer (D-Md.), who said that the Democratic leadership of Congress has no intention of pursuing the summer tax suspension that Clinton touted. The move "would not be positive," he said. "The oil companies would just raise their prices."

Clinton stresses that she, unlike McCain, would push for a windfall-profits tax on oil companies to offset any benefit to them and replace the revenue loss to the highway trust fund. Burman called this "utterly incoherent," saying that a windfall-profits tax would over the long term only exacerbate the supply problems caused by lifting the gas tax, because it would discourage the exploration for and development of new sources of petroleum. "So a policy intended to lower prices, but which won't do that, will be offset with a policy that's likely to raise prices over the long term," he said.

Environmentalists noted that suspending the gas tax also would undermine efforts to curb global warming because it would increase the use of gasoline, a fossil fuel that contributes to climate change. It would also reduce incentives for buying fuel-efficient vehicles and developing alternative fuels. Relying on a windfall-profits tax to replenish the highway fund would leave less to invest in renewable energy, which is what Clinton had previously said a windfall tax would go toward.

More generally, they said, stoking ire about the cost of gas undermines efforts to build a case for limiting carbon emissions, which could raise prices at the pump. "It sends a confusing message," said Kevin Knoblauch, president of the Union of Concerned Scientists. "What's more helpful is if [politicians] help consumers understand that this isn't about near-term gas prices, it's about a comprehensive and smart approach to energy policies."

That leaves the question, though, of whether the proposal will score points on the campaign trail. In Kokomo, Ind., last week, Kathy Spier said the rising cost of gas is to blame for the 50 percent drop-off in sales at her three exotic lingerie stores. "They don't have extra money to spend on frivolous things," she said.

Political consultant Carter Eskew, a former Al Gore adviser, said that if he were advising Obama, he would have said: "If you want to oppose this . . . you're going to have to spend a lot of time and energy explaining.

"I don't think it's brilliant economics; unfortunately, it may be good politics. The smart people say 'It's stupid,' and the people who aren't as schooled say 'At least it will do something for me,' " he said. "I don't know that anyone connects the dots: that there have been a series of politically expedient decisions . . . that have added up to an economic picture that is not at all rosy and in fact fairly disastrous."
