Black voters made up about a quarter of the electorate in Tuesday's Democratic primaries in both North Carolina and Virginia. That's about on par with the 2016 results in Virginia, and represents a slight drop in the share of black voters in North Carolina compared with 2016.
White voters made up about two-thirds in each state, while Latino voters were roughly 5% in each state.

The two Super Tuesday states appear significantly more liberal than South Carolina's electorate, according to these preliminary results. A majority of voters in each state described themselves as liberal in the early exit poll. In South Carolina, it was 47%.
North Carolina's Democratic voters were a bit more apt than those in Virginia to describe themselves as conservative: Fewer than 1 in 10 said so in Virginia, while roughly 1 in 8 said so in North Carolina.
In other words, mixed signals from exit polls, as always. So, let's wait on results.
I would like to say, however, that this whole transition in the narrative from NV to ST has been surreal. Biden has lost 3/4 states quite decisively, and massively underperformed Clinton in SC. Yet, somehow, he's now an electoral super titan.
