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.

When you look at the people that Donald Trump is actually put around him on his Cabinet, this is a pretty - I would argue a very conservative Cabinet. And whether it's on issues of immigration, his pick for the attorney general, very conservative on that issue.

The difference there is that the [Donald] Trump number on change is so much larger than the lead that the other two have in their lanes. And that's going to be the challenge for those other two going forward. The other challenge for Marco Rubio, and this assumption that you're just going to get all those Bush and Kasich voters.

Even on Ben Carson, he's not exactly steeped in housing policy, but his statements on the issue have also been very conservative.

Usually, you do a shakeup because you know that you have a problem or you gaps and you're going to fill those gaps.
