Now, though, lets bring in abc news political analyst matt dowd. Good morning. Thanks for coming in. We appreciate it. So how much should Hillary Clinton be worried about this email imbroglio . I think itll continue to dog her until all the emails come out. The state department hasnt released them all and the Justice Department and fbi finishes their invesesgation. I think this is going to it goes to a vulnerability she has which she continues to have which is on trust and a reminder to voters of the 90s of the part they didnt like about the 90s. It will hurt her in the general election. The question that primary is, does it t dermine her argumentnt about electability with this hanging out there . Right, exactly, and electability is one of the issues hanging over bernie so this is particularly pertinent now. Let me ask you about the republican side. This is where things get truly interesting. What is your view of the state of play right now in the republican side . I think the odds are still that donald trump wins iowa and then in the aftermath of that probably wins New Hampshire. Thats the odds on today. I think the person to watch is marco rubio. Debate, ted cruz had a really bad debate the other night and in the course of that, i think it gives marco rubioioxygen to rise. There is a possibility he could finish second in iowa. If he does that, this becomes a twoperson race between donald trump and marco rubio and its anybodys guess what happens a gamechanging development tentially. Completely. Youll be with us straight through the finish. We appreciate it. News is the plbce to be for complete coverage of the caucuses in iowa.
