Final answer:
Raising gas taxes is politically tricky because the inelastic demand for gas means consumers, rather than producers, bear most of the tax burden, potentially leading to voter dissatisfaction and political repercussions for those who support the tax increase.
Step-by-step explanation:
Raising gas taxes to finance infrastructure is "politically tricky" because the demand for gasoline is highly inelastic and a rise in the gas tax paid primarily by consumers can jeopardize the reelection of politicians. In inelastic markets, like that of gasoline where consumers' demand does not decrease significantly with a higher price, an increase in tax burdens consumers more heavily as they continue to pay for the essential good. Hence, option A is correct. Politicians may avoid raising such taxes due to the risk of losing voter support. The elasticity of supply and demand affects who bears the burden of a tax. If demand is more elastic than supply, producers bear more cost, whereas if supply is more elastic than demand, buyers bear most of the tax burden. In the case of gasoline, where the demand is inelastic, consumers are likely to bear the majority of the tax increase, jeopardizing the re-election of politicians who advocate such measures.
