Scott Rasmussen gives his analysis of Kamala Harris’ new 'sugar high’ in the polls

Veteran pollster Scott Rasmussen explains why presumptive Democratic presidential nominee Kamala Harris has taken the lead in recent polls. “Right now, when we look at all the issues and we ask what voters know about Vice President Harris, well they know that she’s very pro-choice on abortion. They don’t really know anything else about her,” he says.
