Some Alabama Republicans are ignoring US president Donald Trump's call to back their own party's candidate for the senate, Roy Moore, and are instead voting for Democrat Doug Jones. But many others are still backing Mr Moore despite accusations he sexually misconduct made by several underage girls. The race is on a knife edge.
