US President Barack Obama has implored voters to help continue his legacy by carrying Hillary Clinton to victory at the polls in November.
President Obama praised Mrs Clinton at the Democratic convention in Philadelphia, as the most qualified person ever to run for the White House.
He said voters faced a choice between hope and fear, attacking “home-grown demagogue” Republican Donald Trump.
Mr Trump responded by rejecting the president’s optimistic portrayal.
“Our country does not feel ‘great already’ to the millions of wonderful people living in poverty, violence and despair,”
he said on Twitter.
