Eve notes Christopher Hayes's catch that Sarah Palin supported Pat Buchanan in 1999. Neither of them really dwells on the significance of this, so I wanted to back up for those who don't remember the circumstances of the time. This isn't like supporting Buchanan in the GOP primary. When Palin was supporting him, Buchanan was running as a third (actually, fourth) party insurgent, appealing to conservatives who thought George W. Bush was too moderate. This suggests that she's not just a run-of-the-mill movement conservative but a hard-core right-winger.
