US Presidential candidates Hillary Clinton and Donald Trump have cast their votes as the extraordinary US presidential race draws to a close, with the divided nation choosing whether to elect its first woman president or populist Mr Trump.
Chanting "Madam President," about 150 supporters turned out to cheer on the Democratic nominee who voted with husband Bill Clinton at an elementary school near their home in Chappaqua, New York.

"I'm so happy, I'm just incredibly happy," said a smiling Mrs Clinton as she emerged from the polling station, shaking hands, mingling and chatting with people in the crowd, many of whom recorded the moment on their smartphones.
Mrs Clinton told reporters after casting her ballot that it was "the most humbling feeling" to vote for herself as she seeks the nation's highest office.
"I know how much responsibility goes with this and so many people are counting on the outcome of this election, what it means for our country," she added.
"And I will do the very best I can if I'm fortunate enough to win today."
The Republican Mr Trump voted later in his precinct in Manhattan.
After casting his vote, the Republican presidential nominee quipped to reporters that it was a "tough decision" to make his voting choice.
Outside the polling station, at least 100 people gathered on either side shouted "New York hates you!" before a huge media presence as Mr Trump entered and exited.
There were also rival cheers, including from about half a dozen construction workers doing work on the street and wearing hard hats with Trump Pence stickers.
"We'll see what happens," Mr Trump said when asked whether he would concede if the election were called for Mrs Clinton following a bruising, often nasty campaign.
"It's looking very good. Right now it's looking very good. It will be an interesting day. Thank you," Mr Trump added.
Accompanying him were his wife Melania, his daughter Ivanka and her husband Jared Kushner and the couple's daughter Arabella.
Earlier, two unidentified topless women were escorted out of the same polling station, shouting "out of our polls, Trump!" NBC4 News reported.
With their votes cast it is largely a nervous waiting game for the two rivals, who have spent several bitter months at each other's throats.
Mrs Clinton has enjoyed a bounce in her poll standing in recent days and leads her rival by 3.3 points nationally in the rolling RealClearPolitics poll average.
The race is expected to come down to a handful of battleground states like Florida, Nevada, North Carolina and Ohio.
Mr Trump insists he is tied or leading in some states like Michigan and Pennsylvania which have voted Democratic in the last several presidential elections.
