We all knew it was too good to be true.

When President Barack Obama first took office in January 2009, the national average gas price was $1.95, but over most of Obama’s presidency, prices have risen continuously, averaging well over $3 per gallon through much of 2014.

Beginning in the fall of 2014, however, something truly amazing for American consumers occurred: Gas prices suddenly started to fall, and at a rapid pace. According to AAA’s Fuel Gage Report, gas prices in September 2014 averaged $3.39 per gallon, but by January 2015, gas prices had plummeted to below $2.20, with many states like Kansas, Oklahoma, and Texas seeing gas prices fall below $2 for the first time in nearly five years.
