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.
You may not think the article is fair to Obama but it was fact that gas was $1.84 when he took office.
