that the debate rules going forward get a bit more strict. i agree with the idea about this sort of moderate versus progressive debate. warren is pulling away from sanders. she's number two in the polls. he was the basic face in 2016. in some ways he has created this movement but maybe he's not in a position anymore. >> elizabeth warren in first debate was on the first night as well didn't really have anybody in sort of her tier. she kind of had the stage to herself in some regards in terms of not being challenged by other people on the stage.
