The first results are trickling in, with US media projecting wins for the Republican incumbent so far in 13 states including Indiana, Kentucky, Oklahoma, Tennessee and West Virginia -- all states he won in 2016. 

Biden has captured 11 states including his home state Delaware and big prize New York, plus the US capital Washington. As with Trump, so far, all states claimed by Biden were won by Democrat Hillary Clinton in 2016.

So far, that gives Biden 126 electoral votes and Trump 89. The magic number is 270. Observers expect the hotly contested race for the White House to come down to a handful of key battleground states.
