Ruffini collects the tea leaves (including a few that have been bandied about here) adding up to a groundswell of energy behind drilling for more oil here in the U.S. Geraghty notes some of the fuzzy math the Democrats are using to discount the value of drilling here ("note that Democratic Sen. Chuck Schumer uses the magic math to insist that another million barrels a day from Saudi Arabia would bring the price down by $25 a barrel and 62 cents a gallon, while the exact same amount coming from ANWR would lower prices by a penny"), but we've seen the same strategies deployed over the years against tax cuts, and they don't work; if people think the policy's a good one, they are not going to care about dueling projections of how good (by contrast, the Democrats' pick-at-the-numbers approach worked on Social Security reform in large part because Bush foolishly played on their green-eyeshade turf by fighting about "solvency" rather than stressing consumer choice).
Drilling = more supply = lower prices. Voters are not fools, they understand that, and with $4/gallon gas, they will drill their own dogs if necessary to get prices down. And the Democrats are fools if they let themselves get painted as standing in the way of that.
