MIAMI — Hillary Clinton is nearly half way to clinching the Democratic presidential nomination after her strong Super Tuesday.

With 865 delegates at stake, Clinton is assured of gaining at least 490 for the night, having won seven states and the American Samoa. Her double-digit wins in delegate rich states in the South were able to overcome Sanders, who won four states. He picks up at least 323 delegates.

Clinton’s lead widens substantially when including superdelegates, the party leaders who overwhelmingly support her. Her total delegate count is now at least 1,038, giving her 71 percent of the delegates that have been awarded so far. Sanders has at least 410 delegates.

It takes 2,383 delegates to win the Democratic nomination for president.
