As you know, there are Republican and Democratic caucuses in Nevada tomorrow and a pivotal Republican primary in South Carolina. And we'll be bringing you breaking coverage all through the day tomorrow and into the evening.

We'll have our returns scoreboard up as we have on previous primary nights. So if you're a political junkie, we'll have you covered.

We expect the first results to come from the Republican caucuses a little before 1 PM Eastern tomorrow, with the Democratic numbers to follow a couple hours later.

In South Carolina the polls close at 7 PM Eastern.
