Tonight is the third and final presidential debate between Hillary Clinton and Donald Trump.

ABC News political analyst Cokie Roberts talked with WZZM’s Val Lego about the debate and presidential politics hours before the event, which starts at 9 p.m. Wednesday, Oct. 19, on WZZM 13 and online.

Roberts says Trump needs to show more restraint and act more presidential in order to win more voters. And as for his statement that he no longer believes what the polls are saying, Roberts says it’s possible there is some truth to that.

In England and a few other countries, traditional polling has shown to be completely wrong in recent elections.

Roberts says she believes Clinton's strategy going into tonight’s debate will be to remain calm, focused and continue the “when they go low we go high” path she’s been on lately.

But Roberts adds this debate isn’t a cake walk for Clinton. It remains that she struggles with being an engaging and motivating candidate that people can feel attachment to and we’ll have to see if her days of preparation help her.

Roberts also adds that this is the first time she can remember in her many years of covering politics that both politicians are viewed as unfavorable with the voters. A recent poll shows Trump with a 48 percent and Clinton with 47 percent in the unfavorable status.

It will no doubt be a debate to watch once again that could go off the rails at any moment.
