While somewhat accurate, this article is a little disingenuous. Sure, gas prices per gallon were about $1.84 in January 2009 when Oh!Brother took office, but the price of gas in August 2008 near the end of Bush's second term was $4.12.
See: Historical Gas Price Charts
The truth is that gas prices had hovered about between $1.00 and $1.60 per gallon all throughout the 80s and 90s. Once Bush took office in 2000, the price per gallon started its steady climb to where we are today.
