Who might Trump pick as running mate?

Donald Trump's pick for vice president could make or break his hopes of defeating Hillary Clinton in the US election. The New York businessman has spoken of his desire to find a seasoned politician who can help force legislation through Congress and offset his lack of political experience. A sensible choice might help overcome the shortcomings of a 70-year-old who has never held elected office and lags an average of nearly five percentage points behind Clinton in national polls.
