Gov. Pawlenty Mocks Obama With Tire Gauge

The Minnesota governor -- and possible McCain VP -- lampoons Obama's call for Americans to conserve gas by inflating their tires.

In Iowa, holds up gauge and says: "It will very mildly add to your fuel efficiency, but checking the air pressure in your tires is not an energy policy for the United States of America."

Also calls supporting Obama "the political equivalent of bungee jumping."
