Normally I like anything that stimulates travel, but John McCain's proposal to suspend the gas tax for the summer strikes me as populist pandering. No one likes taxes, sure, but come on—does he really think this is going to help the economy? And for the earth's sake, we all need to be more mindful of how much we drive, and there's a strong argument that summer is exactly when we don't want people driving more, more, more. I grew up in southern California but haven't lived there in years, but I can still remember those horrific summer days when the temperature was high and air quality was poor. It's something we should be trying to avoid, not fostering. But maybe there's a case for it that I'm missing?
