The most frequent way that I will communicate with him Obamacis when we're traveling. We talk about what's in the news, and I hear him talking about issues that are important to him.

There was also a sense that if he [Obama] did not win in Iowa, that it was very unlikely that he would be able to come back and win the Democratic nomination and win the general election. It was sort of an all-or-nothing bet. The stakes were that high.

My start in politics was watching my parents go to the polls on election day. It reminded me that being an active, engaged citizen and voter is critical to the success of our democracy.

We have marched in lockstep with Israel. We've been side by side with them as they've confronted the Iranian nuclear threat and we'll continue to be. All options do remain on the table. That's something that we've said all along. That continues to be the case.

We would welcome that, but it's going to require a commitment on the part of the North Koreans to denuclearizing the Korean Peninsula and pursuing a stable relationship with their neighbors. Instead, we've seen a lot of provocations and a flouting of international norms and obligations.

Even now, hearing the debates about Medicaid, the suggestion that somehow we could save money by cutting Medicaid strikes a chord in me personally. It seems there are some other ways we can save money rather than making it harder for people like my aunt to get health care.

I still remember vividly watching television coverage of the Democratic National Convention in the summer of 1992 (when he was 17) when Bill Clinton got the nomination. That was certainly a part of my growing interest in politics.
