Most important, you can have a war room, you can have a war plan, but if your general - in this case, it's Donald Trump - isn't following the plan and is tweeting or is going and giving interviews that contradict the plan, then none of this really matters.

When Jeb Bush came on the shows and couldn't answer questions about Iraq, and when he looked like he was unsteady, it absolutely solidified the concerns that they had had all along about his skills.

It doesn't need to be deep and it doesn't need to be a 65-point plan, but just to give some concrete examples of how this economy is going to work for the people that feel right now it's not working for them, and then finally to get to central tension of this campaign. This is a presidential campaign where you have Americans now who want to see change. And Hillary Clinton is the status quo. How can she be both status quo and change?

Hillary Clinton is got to make the case for herself that nobody else can make, and for voters to see somebody who looks more three-dimensional, that's not simply a caricature that had been sort of a part of the American dialogue for the last 25 years.

Lots of people coming in and out the Trump Tower, not necessarily indicative of what Donald Trump policy is going to be. To have Al Gore one day, and the next day the head of ExxonMobil, what does that - what are you supposed to read into that about his stance on climate change? So, I think, again, it's going to be that the actions that he takes are significant.

The Donald Trump call in the president of Taiwan and of itself, as Henry Kissinger said, hasn't created some tremendous trouble in China. But what we don't know is whether this is just posturing or whether this is a policy change.

It's never a good time, when you're the president of the United States and your own party is finding lots of different ways to distance themselves from you.
