President Barack Obama on Thursday (IST) painted an optimistic picture of America’s future in a speech on Wednesday aimed at giving full-hearted support to Hillary Clinton to help her defeat Republican rival Donald Trump and become the first woman elected US president. “There has never been a man or woman, not me, not Bill (Clinton) – nobody more qualified than Hillary Clinton to serve as president of the United States,” Obama said to cheers. Speaking to the Democratic Party convention in Philadelphia, Obama offered an alternative to businessman Trump’s vision of the United States as being under siege from illegal immigrants and terrorism and losing its way in the world. “I am more optimistic about the future of America than ever before,” Obama told cheering delegates at the Wells Fargo Center.
