I mean, Biden voted for the AUMF too and most Dems have been dreaming wistfully of a universe where he cames into this election sweeping everyone off their feet. Not to defend their votes but even Iraq skeptics cast in its favor, largely because they felt by adding their voice Bush would for some reason feel compelled to listen to their council & their provisos, eg to go through the UNSC / inspections process in good faith and not just say "fuck it" and start giving countdown demands no one could possibly adhere to... I mean I really don't want to give excuses for these votes but my overall point is this isn't just something you pin on Hillary with your arms crossed. There are a lot of shameful "Yea"s in that list.
