country that we need revenue. we have major deficit problems and we need to invest in each other. infrastructure, education. research and development. talking about that is important. i want to keep coming back to the fact the timpdifferences ben us in democrats are so small. compared to the goal and the president of the united states. how we can treat each other is coming together or play to the benefit of donald trump. i don't want to give him any advantage. of doing the work of the rnc. we have to have differences but in a way that we can unify after this election. >> we're getting closish. to iowa. >> the top three candidates are warren, biden and sanders. state by sate. suggest it's consistently stayed those top three. why have you had trouble breaking through so far?
