London, July 26 : US presidential hopeful Barack Obama's 67-year-old step mother, Kezia Obama, believes that he will change the way the world thinks once he takes charge at the White House in Washington.
As he arrived in London on Saturday, Kezia Obama, Barack Senior's first wife, said proudly: "The things Barry Junior says are the things the world needs to focus on."
"I believe he's the right person at the right time. He's the one to make the changes we need. If he does win he will be a president for the whole world," The Mirror quoted her, as saying.
Kezia describes herself as Barack's "African mum" and she says she was overcome with emotion on hearing his rousing speech in Berlin.
She said: "It was such a wonderful feeling. I had to cheer at the television as he spoke. It made me so happy.
"I don't look at him as a black person but I know outsiders see that and I know it's important.
"I realise the huge significance the colour of his skin has and what a massive breakthrough he has made for black people. He will show that colour is not important."
