This is a tough environment, and it's tough for everybody.

There have been two Geraldo Riveras through his long career. One of them was a reporter who has done some remarkable work. The other was a television show host who did what it took to get an audience.

How can we be isolating ourselves when it's 16 to 3 in NATO for what we want to do?

My sense about Greta is that people ought to wait and see and see if she doesn't indeed turn out to be as balanced as we hope and expect she will. But there you are.

Geraldo has been in Lebanon. He has done some excellent reporting out of there, and of course, we now know by virtue of the president's speech on Tuesday night that the terrorist organizations that operate in that area are now on the list.

Ted Cruz has struggled, and Donald Trump, of course, has been the big winner the last two outings. And the polling that we have, some of it is a week old. In fact, I think that's the latest poll suggests that he has a strong lead here. And therefore should be expected to win.

If the markets had behaved badly, that would obviously add to people's sense of alarm... but there has been a lot of reassurance coming, particularly in the way the Brits handled all this. There seems to be no great fear that something like that is going to happen here.
