The Billy Bush Saturday to me is a litmus test.

Its a litmus test, he said.

Its a line I remember from the movie,The Wild Bunch.

William Holden uses it right before that huge gunfight at the end.

When you side with a man, you side with him, okay?

The good and the bad.

And thats what Billy Bush weekend showed me.

Billy Bush Saturday showed me who really had Donald Trumps back to play to his better angels.

Bannon added that people didnt care about the tape.

They knew Donald Trump was just doing locker room talk with a guy.

And they dismissed it, he said.

It had no lasting impact on the campaign.

Trump went around the room and asked people the percentages he thought of still winning and what the recommendation.

His own response was to tell Trump that he still had a 100 percent chance of winning the election.

Thats the first time and only time [Trump] ever got upset with me, he said.

He goes, Come on, its not 100 percent.

I go, Its absolutely 100 percent.

And I told him why.

They dont care.'
