Here is a good piece, with good graphics, from Flopping Aces about which political party is most responsible for high gas prices in the US. (Hint: it's not Republicans.) Democrats have wanted high gas prices for a long time. Kerry said that in the last Presidential election. The Democrats cause the prices to be high and blame it on Republicans. They don't call Republicans the "stupid party" and Democrats the "evil party" for nothing.
