That’s the flaw in viewing this year with the same models as 2008 and 2012 - as they didn’t have a significant 3rd party presence. This one, the leader is in the mid 40s, so lots of room for shifting.
Unfortunately, this might plausibly include some shifting to Hillary as well.
I think Hillary has just about all the votes she is going to get. Any peel off from third parties will go to Trump now, or the vast majority of it anyway.
