I think you still have a problem here when you're going and you're looking not just that Trump is winning, but he's winning in a broad swath of voters.

Lots of people coming in and out the Trump Tower, not necessarily indicative of what Donald Trump policy is going to be.

The only problem with the "children of Reagan" line is it reminds you that Marco Rubio is the young candidate.

If you're Chris Christie, who is governor of New Jersey, a state that obviously was impacted by 9/11, this gives you an opportunity to talk about how, as governor, you had to deal with terrorism and security issues.
