I don't know if Mary Landrieu really thinks that ramming Keystone XL through Congress will save her job, or if it's just an audition for another job, but either way it's a pretty crappy way to end a Senate career.
It's a funny issue, really. Sure there's money behind it and all, but basically the Morning Joe crowd spends time obsessing about it because hippies don't like it. Why else would they care about using eminent domain to build a pipeline so a Canadian company can export oil?
