LONDON (Reuters) - Democratic candidate Joe Biden was back as clear favorite to win the U.S. presidential election in online betting markets on Wednesday, a reversal of fortune for President Donald Trump who had been favoured overnight.

The shift, according to data from three odds aggregators, came after Biden overtook Trump in the battleground state of Wisconsin, with an estimated 95% of the vote tallied there.
