Bernie Sanders

In the wake of three straight weeks of lopsided multistate losses to former Vice President Joe Biden, Vermont Sen. Bernie Sanders is now "having conversations with supporters to assess his campaign," according to a top aide.

For the third straight primary Tuesday, Joe Biden emerged as the winner.

But the country is in a vastly different state than it was just a few weeks ago, and as a result, the former vice president's victory address on Tuesday night was hardly celebratory.

"Tackling this pandemic is a national emergency akin to fighting a war," the Democratic front-runner said in prepared remarks from his home in Wilmington, Del.

In what have turned out to be the last presidential primary elections in the month of March because of the novel coronavirus, Joe Biden swept all three states Tuesday by big margins and appears well on his way to being the Democratic nominee.

The former vice president won Florida by almost 40 points, Illinois by more than 20 and Arizona by double-digits, too.

It was a remarkable night that adds to Biden's delegate lead that, at this point and because of how Democrats allocate their delegates, looks insurmountable.

Amid the coronavirus pandemic, the 11th Democratic presidential debate, on Sunday, is set to look and sound quite different from the previous 10.

To prevent further transmission of the virus, the Democratic National Committee announced Thursday it will hold the debate in Washington, D.C., with no live audience, instead of its original planned location of Arizona, one of four states voting on Tuesday.

Super Tuesday has passed, but many events lie ahead in the 2020 election season. Many states still have primaries, and there are more debates, as well as this summer's party conventions.

Bernie Sanders is staying in the race for president, but he made it obvious on Wednesday that he sees Joe Biden's clear path to the nomination.

"While our campaign has won the ideological debate, we are losing the debate over electability," Sanders said. The recent underdog added that he disagrees that Biden is the stronger candidate to take on President Trump, "but that is what millions of Democrats and independents today believe."

WASHINGTON (AP) — The Democratic presidential contenders have some inconvenient truths to grapple with.

It's not easy, for example, to summon foreboding words on the economy — accurately — when the U.S. has been having its longest expansion in history.

Health care for all raises questions of costs to average taxpayers that the candidates are loath to confront head on.

MADISON, Wis. (AP) — U.S. Sen. Bernie Sanders returned to the friendly terrain of Wisconsin on Friday, promising to build a coalition that will defeat President Donald Trump as he kicked off a swing through pivotal states that are part of the Democratic "blue wall" strategy for 2020.

Sanders, speaking to a crowd of about 2,400 who braved 40-degree (4 Celsiu) temperatures with a stiff 20 mph (32 kph) wind, pledged to flip Midwestern states such as Wisconsin that Trump narrowly won in 2016.

DENMARK, S.C. (AP) — The issue of workers' rights is a focus this weekend for some of the Democrats running for president.

At a rally in Warren, Michigan, where General Motors is closing a plant, Vermont Sen. Bernie Sanders called on President Donald Trump to "go back to the drawing board" on the United States-Mexico-Canada Agreement, the tentative pact that would replace NAFTA. Sanders said the newly negotiated deal, which has yet to clear Congress, would still let companies such as GM continue to send U.S. jobs to Mexico.
