Well lookee here...a website that tracks petroleum industry campaign contributions, called Follow the Oil Money.

I did a zip code/name search, and not surprisingly, Texas and Louisiana congressmen received quite a bit of campaign funds from the oil industries and they voted for "big oil" 65-100% of the time.

And did you know that George W. Bush received $2,649,725 in oil contributions during the 2004 election campaign? John Kerry received $184,037. In 2008, Rudy Giuliani received $659,158 and Barack Obama received $163,840. The presidential races page told me so.

Their visual charts are pretty amusing. They compare them to Facebook or MySpace, "in which companies and politicians have become 'friends' by giving money".

For more information, including how they get their data, go to FAQ page.
