LISA BOOTHE (CO-HOST): The danger of Bernie Sanders and his movement is that a lot of these policies on their face are popular with the American people and that's what makes them so dangerous because of the economic toll they would take on this country. So President Trump's best saving grace is to have a strong economy, to say, “Look, we don't want anyone taking us in a different direction. We're on the right path. The economy is strong, it's booming, people are doing better.” That's President Trump's best saving grace against these types of policies. Also being able to take it a step further and explaining why these policies are bad. But the way I look at Bernie Sanders, if you think about a crowded primary field, there's 20 something people on the stage. Who's the person that's going to draw attention? Who's the person that's the most unique? When there's not a lot of daylight between the candidates on the policy issues, it's going to be the candidate that stands out the most. The one that can generate the kind of excitement, and Bernie Sanders is the only one that's generating this kind of excitement. A week after he announced, he talked -- boasted the fact that he had a million people sign up to volunteer for his campaign in every congressional district around the country. What other candidate is doing that?
