You can. I did not like her Iraq war vote for starters. She was very much in favor of the war on drugs. Although she said different words during her campaign- there was absolutely no doubt where she came from. She was adamantly opposed to single payer health care. There's more- but I am a west coast liberal/Progressive and she just didn't fit the part at all. Clearly I wanted Sanders as the nominee in 2016. She was who the DNC wanted so that's who we got. She always came across as someone who didn't really like people-
Although never my first choice- I would vote for Warren if she stayed in and became the nominee- but we know that will never happen.
