Former Democrat Vice President Joe Biden won at least eight large states on Super Tuesday. His rival Bernie Sanders won the biggest prize of California to set up a long one-on-one battle for the Democratic presidential nomination. However, the results left Michael Bloomberg, the billionaire former New York mayor who spent more than half a billion dollars on advertising, largely out of the running.
His only victory was in the US territory of American Samoa.
Mr Bloomberg campaign officials said he would reassess whether to stay in the race on Wednesday, but that did not mean he would drop out.
Mr Bloomberg also did not escape the wrath of incumbent President Donald Trump, who gave him a scathing nickname of “Mini Mike”.
He tweeted: “The biggest loser tonight, by far, is Mini Mike Bloomberg.

“His “political” consultants took him for a ride.
“$700 million washed down the drain, and he got nothing for it but the nickname Mini Mike, and the complete destruction of his reputation.
“Way to go Mike!”
Later in the evening, he also posted a video of Mr Bloomerg eating a snack, which appeared to be pizza, while the results were being announced.

Mr Blomberg did not appear to be deterred by Mr Trump’s comments.
After the results, he tweeted: “Thanks to our supporters who went to the polls, knocked on doors, made phone calls, and sent texts to friends.
“We couldn’t have done this without you.
“We’re 100 days into our campaign – and we’re more determined than ever to defeat Donald Trump and rebuild America.”
Meanwhile, Mr Biden rolled to wins across the South, Midwest and New England as Americans in 14 states voted for a Democratic challenger to Mr Trump in the November 3 election.
“They don’t call it Super Tuesday for nothing,” Mr Biden, the former vice president who had performed poorly in the first three nominating contests but broke through with a win in South Carolina, told roaring supporters in California.
“We are very much alive,” he said.
Mr Sanders, the one-time front-runner who had hoped to take a big step toward the nomination on Tuesday, was projected by Edison Research to win in his home state of Vermont, Colorado and Utah. Fox News and AP projected Sanders won California.
