What else would explain their love for a gas tax holiday? To anyone with even a modicum of economic understanding it is an absurd idea. Demand for gasoline is fairly inelastic, and in the short run is quite close to perfectly inelastic. Thus, gas prices will stay right about where they are prior to the tax holiday. So, who does this benefit? Not you! Unless you're a big oil company, who will see their profit margins increased.
Oh, and what about the millions of dollars this will cost the Highway Fund? And the jobs that will be lost due to lack of project funding?
Stupid. Stupid. Stupid.
