Former First Lady and US Secretary of State Hillary Clinton has secured enough convention delegates to get the Democratic Party nomination for President of the United States of America.

The Associated Press combined the number of delegates Mrs. Clinton has won in the primaries and party caucuses so far with so-called super delegates - party officials who are appointed by party officials rather than selected by voters.  After a telephone canvass of the supers, the AP determined that Cliton has reached the magic number of 2,383.

This latest development comes after a year of twists and turns in the least-traditional US election in modern times.  It's also on the eve of major primaries in California, New Jersey and other states. 

"I got to tell you, according to the news, we are on the brink of a historic, historic, unprecedented moment, but we still have work to do, don’t we?" Hillary Clinton told the crowd at a big rally in Long Beach, California.  "We have six elections tomorrow, and we're going to fight hard for every single vote, especially right here in California."

Hillary's rival Senator Bernie Sanders is adding his own plot twist by refusing to accept the AP's rolling tally and vowing to fight on.  His campaign insists that the super delegates should not be counted until the Democratic National Convention in Cleveland in July.  And even some of Mrs. Clinton's major supporters say the AP jumped the gun and declared her the presumptive nominee too soon.

Even so, Hillary Clinton leads Bernie Sanders in the popular vote.
