Chappaqua, United States: Hillary Clinton cast her vote early Tuesday near her home in New York state, as America chooses whether to make her its first woman president, or elect the populist Donald 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.

‘I'm so happy, I'm just incredibly happy,’ said a smiling Clinton as she emerged from the polling station, shaking hands, mingling and chatting with the crowd.

‘All my friends and my neighbours, it makes me so happy.’
