Behind every great gasshat is.. another gasshat, and Congress is full of them. The Senate just voted to support an amendment that recommends President Obama build Keystone XL. If you're upset by that there are a number of groups you might want to pitch in with, like this page on Friends of the Earth.
The vote isn't binding, but it's certainly embarrassing for Congress. According to Oil Change International, Senators for the amendment received 3.5 times more campaign contributions from fossil fuel interests. How can anyone see those numbers and not think of those Senators as on the take?
