The caucus still seems pretty tilted toward Clinton 2016 voters (55 percent voted for her, compared to 30 percent who went for Sanders). Among the Clinton 2016 group, Biden, Buttigieg and Warren are all doing better, while Sanders is getting the majority of the Sanders 2016 caucusgoers — so far, more than preelection polls seemed to indicate. Among those who supported neither in 2016, Buttigieg is doing well.
