Did you bother to do ANY research on this? At all?
Here's Krugman. I know you'll trust him, because he's quite the pro-Hillary blogger.
Why doesn't cutting the gas tax this summer make sense? It's Econ 101 tax incidence theory: if the supply of a good is more or less unresponsive to the price, the price to consumers will always rise until the quantity demanded falls to match the quantity supplied. Cut taxes, and all that happens is that the pretax price rises by the same amount. The McCain gas tax plan is a giveaway to oil companies, disguised as a gift to consumers.
Is the supply of gasoline really fixed? For this coming summer, it is. Refineries normally run flat out in the summer, the season of peak driving. Any elasticity in the supply comes earlier in the year, when refiners decide how much to put in inventories. The McCain/Clinton gas tax proposal comes too late for that. So it's Econ 101: the tax cut really goes to the oil companies.
The Clinton twist is that she proposes paying for the revenue loss with an excess profits tax on oil companies. In one pocket, out the other. So it's pointless, not evil. But it is pointless, and disappointing.
Comprende? The OIL COMPANIES save the money. Not the gas stations, not the consumer, nobody else. The McCain/Hillary plan is pure shill designed to buy the votes of uninformed people such as yourself.
Do you honestly - honestly - think that a gas tax relief is going to be passed this summer?
The only real answer you can give is no; because you know in your heart it isn't going to happen, it'll never get through Congress, and even if it did, Bush wouldn't sign it, and even if HE DID, IT WOULDN'T TURN INTO LOWER PRICES AT THE PUMP. Nothing about this issue is real. Hillary isn't doing shit to help you or anyone else on this issue. She's trying to buy votes from people who don't understand how gas pricing works!
