United States Studies Centre fellow Bruce Wolpe says that Joe Biden will be an ‘instant front runner’ in the race for 2020 Democratic presidential nomination when he announces his debut. Speaking with Sky News on Wednesday, Mr Wolpe has said the former vice president will enter the race by video on Thursday morning, local time. He says the Democratic race is going to be ‘even bigger and more rowdy than the Republican race in 2016’, with 20 people in the running.
