1. Donald Trump wins South Carolina

Donald Trump was the clear winner of the South Carolina Republican presidential primary, leading with roughly 33 percent. Sen. Marco Rubio (R-Fla.) and Sen. Ted Cruz (R-Texas) were in a near-tie for second, with each candidate between 22 and 23 percent. The big win clearly distinguishes Trump, who finished a close second in Iowa and won convincingly in New Hampshire, as the frontrunner for the Republican presidential nomination.

2. Hillary Clinton wins Nevada caucuses

Hillary Clinton won the Nevada Democratic caucuses on Saturday. Clinton led Bernie Sanders roughly 53 percent to 47 percent. The victory in Nevada surely comes as a big relief to the Democratic frontrunner, who prevailed very narrowly in Iowa before getting thumped by Sanders in New Hampshire. Next up for the Democrats is next Saturday's South Carolina primary.
