Clinton making history as US votes in last big primaries

Newyork: Americans voted Tuesday in the last major state primaries of the 2016 White House race from New Jersey to California, after delegate counts showed Hillary Clinton clinching the Democratic nomination.

The results are expected to see Clinton declare victory as the first woman in US history to secure the presidential nomination of a major party, putting her on course for an unprecedented showdown with New York billionaire Donald Trump, the presumptive Republican party nominee, in November's general election.

Her self-declared Democratic socialist challenger Bernie Sanders has so far ignored media reports that she has already clinched the magic number of delegates. He is chasing a win in California, the country's most populous state, and insisting the nominee will not be chosen until the party convention in July.

Voting was underway in six states -- New Jersey, California, New Mexico, Montana, North Dakota and South Dakota. New Jersey and the Dakotas will be the first polls to close at 8:00 pm Eastern time (0000 GMT Wednesday).

It remained unclear what effect the US media reports that Clinton had passed the milestone of 2,383 delegates late Monday to secure her status as the presumptive Democratic nominee would have on those casting ballots Tuesday.

"I'm a Bernie Sanders guy all the way." said 21-year-old student Saul Gomez, voting in Los Angeles. "Honestly he seems a lot more genuine to me," he said. "He's consistent, and I dig that."

Clinton -- the 68-year-old former first lady, New York senator and for four years Barack Obama's top diplomat -- is scheduled to deliver a victory speech in Brooklyn late Tuesday in perhaps the pinnacle of her political career to date.
