Biden claims 10 Super Tuesday victories, Sanders takes 3 but leads in crucial California

A resurgent Joe Biden scored victories from Texas to Maineon Super Tuesday, revitalizing a U.S. presidential bid that was teetering on the edge of disaster just days earlier.

Biden took Texas, Alabama, Oklahoma, Tennessee, Minnesota and the battleground states of North Carolina and Virginia, a strong start as 14 states and one U.S. territorywent to the polls. He also won the solidly Republican state of Arkansas and Elizabeth Warren's home state of Massachusetts, and was ultimately declared the winner on Wednesday in a tight race in Maine, too.

His rival, Bernie Sanders,countered with a winin his home state of Vermont, Coloradoand Utah and was leading in the crucial, delegate-rich California.

Suddenly, the Democratic Party's presidential field, which featured more than a half dozen candidates a week ago, transformed into a two-man contest.

Biden and Sanders, lifelong politicians with starkly different visions for America's future, were battling for delegates in a of high-stakes elections that marked the most significant day of voting in the party's 2020 presidential nomination fight.

Former U.S. vice-president Joe Biden goes after both his Democratic opponents and Donald Trump as he implores people to vote for him.

It could take weeks or months for the party to pick one of them to take on President Donald Trump in the November general election.

But the new contours of the fight between Biden and Sanders crystallized as the former vice-president and the three-term Vermont senator spoke to each other from duelling victory speeches delivered from opposite ends of the country Tuesday night.

"People are talking about a revolution. We started a movement," Biden said in Los Angeles, knocking one of Sanders' signature lines.

Without citing his surging rival by name, Sanders swiped at Biden from Burlington, Vt. "You cannot beat Trump with the same-old, same-old kind of politics," Sanders declared, ticking down a list of past policy differences with Biden on Social Security, trade and military force.

"This will become a contrast in ideas."

New York billionaire Mike Bloombergdropped out of the race Wednesday andWarren wasmeeting with her campaign to determine whether there was any reason tostay in the race.Shefinished in an embarrassing third place in her home state, and did not win in any of the states that voted.

The balance of Super Tuesday's battlefield raised questions about whether the Democratic primary contest would stretch all the way to the July convention or be decided much sooner.

Biden's strong finish punctuated a dramatic turnaround in the span of just three days when he leveraged a blowout victory in South Carolina to score sweeping victories on Tuesday that transcended geography, class and race.

The former vice-president showed strength in the U.S. Northeast with a victory in Massachusetts and Maine. He won delegate-rich Texas in the Southwest, Minnesota in the upper Midwest and finished on top across the South in Virginia, Alabama, North Carolina, Tennessee and Arkansas in addition to Oklahoma.

Across the Super Tuesday states, there were early questions about Sanders's claims that he is growing his support from his failed 2016 presidential bid.

Sen. Bernie Sanders tells his supporters whose votes he needs in his movement to beat Donald Trump in November.

Biden bested him in Oklahoma, though Sanders won the state against Hillary Clinton four years ago. In Virginia, where Democratic turnout this year surpassed 2016's numbers by more than 500,000 votes, Sanders's vote share dropped significantly.

And in Tennessee, Democratic turnout was up more than 30 per centfrom 2016, but Sanders's raw vote total was only a few hundred votes greater than four years ago.

Warren fought to be optimistic Tuesday night.

Facing a roaring crowd in Michigan before news of her disappointing home-state finish was announced, she called on her supporters to ignore the political pundits and predictions as her advisers insist she's willing to go all the way to a contested convention in July even if she doesn't claim an outright victory anywhere.

"Here's my advice: Cast a vote that will make you proud. Cast a vote from your heart," Warren declared. She added: "You don't get what you don't fight for. I am in this fight."
