So, I guess the important question is which effect will have a larger impact on the presidential election and whether the salience of the "gas prices" issue in political analysis will be diminished due to this analysis.The disparities are stark: Wyoming drivers pay $3.21 per gallon while drivers in California pay $4.34. And, oddly enough, the differences line up well with partisan patterns — Houser found that blue states pay significantly higher prices per gallon than red states.
But here’s the catch: Red states may enjoy cheaper gasoline, but they also tend to be less dense and have less-efficient vehicles, and their residents tend to drive more miles each day. Wyoming residents may pay less per gallon, but they use more gallons of gasoline. And this is a consistent pattern: Houser found that deep-red states are actually shelling out more for gasoline as an overall percentage of their income.
