And they didn’t ask about Johnson or Davis, so we can’t tell which way the undecideds are leaning.

22% undecided, when both candidates have near universal name recognition, is a very volatile race.

How many “undecideds” are really pro Trump, but don’t want to tell strangers that?

My guess is more than a few.

If you consider Clinton as the "incumbent," then this looks very bad for her. Undecideds usually break for the challenger. Clinton campaign knows this, and has to try to counter it with hysterical fear mongering. Likely to over reach and backfire.
