Prop Watch: The Obama Tire Gauge

It's prop day on the campaign trail. To coincide with Barack Obama's energy speech this morning, the McCain campaign handed out tire gauges branded with the slogan "Obama's Energy Plan" to reporters traveling with the senator today. (The Republican National Committee apparently will distribute others to reporters back in DC and at the Obama event today in Michigan.) The gauge is poking fun at Obama's comment last Wednesday that Americans can save energy by "making sure your tires are properly inflated." Nevermind that plenty of Republicans have offered up similar advice—prominent McCain surrogate Gov. Arnold Schwarzenegger, among them—the McCain campaign is pushing that message that Obama is so lacking in judgment that he thinks inflating the tires alone is the key to solving America's energy problems. Merits of the debate aside, how did the GOP get these gauges engraved so fast?
