don't forget we have the nevada caucus in between those. think it's reflective of where we see the race. the most important thing is that i think joe biden has stabilized his race. there was a lot of talk about his decline and whether he would have the money and whether his support would stick with him. across all of these states we've seen him hold pretty strong in place over the last couple of weeks, which is really critical for him. but going back to your point, over 50% of primary and caucusgoers still say they're open to changing their mind. among second choice voters say they're relatively even between all of these particular races. i still believe we're going to see a lot of change, more change between now and the iowa caucus than we have so far this year. >> so we talk about it all the time, mike, black voters in south carolina, 44% support joe biden. that remains the wall that mayor pete is going to have to break through if he wants to become the democratic nominee.
