What Went Down On Super Tuesday

ABC News is projecting Colorado for Sanders, which was good state for him to begin with, and one that was going to be very hard for Biden to catch up in because it’s entirely vote by mail.

While Biden has done well in states with a fair bit of racial and ethnic diversity, especially states with sizable black electorates, it’s notable that he looks in good shape to win in Oklahoma, a state with about an 80 percent white primary electorate. However, it’s not like he won by huge margins among white voters there — in the preliminary exit poll, he led Sanders by 11 points, 34 percent to 23 percent, with Bloomberg getting 16 percent.

As we expected, the states today differ quite substantially in terms of the racial composition of the electorate, ranging from 95 percent white in Maine to 44 percent white in Texas. Texas and California also have substantial Latino shares of their populations — 32 and 28 percent, respectively — while Tennessee, North Carolina, Virginia and Alabama have large black shares of the Democratic electorate. And as Geoff pointed out, all four of those latter states have been called for Biden, in large part because of his overwhelming lead among black voters.
