Whenever there's a candidate that is "too liberal" one of the main narratives that gets expressed by our glorious political press is that the candidate's supporters are stupid. You're stupid for supporting someone who is liberal because they're unelectable, and you're stupid for thinking that too liberal candidate is actually liberal because you're stupid, you stupid liberals.
There are lots of low information voters out there. I'm sure even high information voters don't know every single detail about Bernie's career, but they probably are relatively well acquainted with the last 15 years or so of it. I'm not making the case for Sanders, just commenting on the inevitable narrative which is: liberals are stupid.
