Pete Buttigieg dropped out of the race for the Democratic presidential nomination on Sunday, saying he no longer saw a change of winning, the day after fellow moderate Joe Biden won a big victory in South Carolina.

The move shook up the Democratic contest to pick a candidate to take on Republican President Donald Trump in November's election and came two days before the 14-state Super Tuesday nominating contests that will offer the biggest electoral prize so far.

Buttigieg, a 38-year-old former mayor of South Bend, Indiana, who gained early momentum after he narrowly won the Iowa caucuses last month and finished a close second in New Hampshire, had sought to unite Democrats, independents and moderate Republican voters. But he finished a distant third in Nevada and fourth in South Carolina.
