Helpful chart by state, showing how much we each pay ALREADY in TAXES for a gallon of gasoline (as of 2013):

I pay 65 cents in TAXES for each gallon in Wisconsin. Ranked #14.
Guess who is the highest? Yep. New York.
When you figure in the sales tax we pay on gas, Michigan may be even higher than NY!
