Bush vs Obama in Gas prices

Something was said the other night that I wanted to find out more information. The lady claimed that this is the first time since Obama took office that I haven't paid Five dollars. Everyone knows that gas prices have nothing to do with the presidents! Here's a map that I found. Obama took office in January 2009

As you can tell that Gas prices hit an all time high right before Obama was ever elected president. Some people need to do their researched before they open their mouth!
