I observed something interesting about Trump's behavior over the past several weeks. First was at a townhall or similar venue when he was asked what he should do about the hardworking undocumented people. To my surprise, he asked the audience. They said these undocumented folks shouldn't be considered the same as the undocumented people who are criminals, etc. It struck me as a very unusual act for such an alleged "dominator".

Then he did it again on the clip of the Dr Oz interview, asking the audience if he should turn over doctor's letter.

The most interesting thing, though, was how, when the pastor of the church in Flint chided him for making his remarks politics, he completely deferred to her. I know later, on friendly turf at Fox he denigrated her, but his original deference was astonishing.

It made me wonder why. After mulling it over, I thought deep down Trump must be really insecure. Imagine my surprise when Tony Swartz, author of "Art of the Deal" told sub All In host Joy Reid that it wasn't well know, but Trump is very insecure.

I think this knowledge will help Hillary a lot in the upcoming debates.
