A resounding victory in South Carolina has thrust Joe Biden back into the race for the Democratic presidential nomination, but that could all change in two days when voters go to the polls in 14 "Super Tuesday" states.
With 48 per cent of the vote in South Carolina, the former vice president more than doubled the 20 percent won by national frontrunner Bernie Sanders, reviving Biden's campaign and positioning him as the senator's leading rival.
"This is a big boost for us," Biden said Sunday on CNN, but "we have a long way to go."
The 38-year-old former mayor repeatedly told NBC that his focus now was to do "what is best for the party" in order to "end the Trump presidency."
"We'll be assessing at every turn," he said, "not only what the right answer is for the campaign, but making sure that every step we take is in the interest of the party and that goal of making sure we defeat Donald Trump."
"At the end of the day," he told ABC, "I have known Joe Biden for a very long time. He's a decent guy. I have no doubt if I win he'll be there, and if he wins, I'll be there."
The 78-year-old said he was sure Democrats would come together in the face of a president he said was "a pathological liar, running a corrupt administration."
