Our Ever Rising Gas Prices

Oil prices are very much on the rise, but gasoline has not yet caught up. When it does, $4 a gallon may sound like the good old days. President Bush says there's no "magic wand" for the government, but the candidates to replace him have other ideas. John McCain and Hillary Clinton want a summer holiday on the federal gasoline tax. Barack Obama calls that a "gimmick" that could make matters worse. We look at their different proposals.  Should gasoline taxes actually be higher to encourage conservation, something they all support? Is this the just beginning of "painful adjustments" to new, global realities?
