And how would that be regulated?

I drive a Ford Explorer. I also own a Dodge Caravan and a Volkswagen Jetta. They all use gasoline, as does my lawnmower. Each uses a gallon of gas to a different level of efficiency.

Would you propose the converse approach, as well, which would allow someone buying gas for a lawn mower to pay only pennies per gallon? How would you ensure that someone filling a gas can, ostensibly for their lawn mower, doesn't empty that gas can into their Humvee?

Or is this, again, just more liberal whining without a plan?
