Hillary can’t win... The only group of undecideds who could possibly break her way are youn folks too young to be politically aware in the 90, anyone else who hasn’t yet broke for Hillary isn’t going to.
She’s got solid D support and losing I’s badly. Only reason Trump isn’t polling up 10 consistently are the never trump/GOPe folks on the right who are R and are just sour graping as much as they can. By Nov most will have returned home.
There are no undecided. Everyone knows whom they will vote for. It is already decided.
