2020 Elections

Updated at 11:36 a.m. ET

Tulsi Gabbard, the Hawaii U.S. representative and Iraq war veteran who has stirred controversy within her own party, is suspending her bid for the White House.

She had been one of only three candidates left in the race for the Democratic presidential nomination, despite only garnering two delegates.

Gabbard made the announcement in a video posted Thursday morning, and said, "It's clear that Democratic primary voters have chosen" former Vice President Joe Biden to be the person to take on President Trump in November.

The U.S. has had two recent presidential elections in which the winner of the popular vote — Al Gore in 2000 and Hillary Clinton in 2016 — ultimately lost to the challenger for the seat.

That's because the U.S. has an Electoral College — each state gets a number of votes (by representative electors) in the Electoral College that's proportional to its population. And 48 of the 50 states (Maine and Nebraska are the exceptions) have been awarding those electoral votes on a winner-takes-all basis.

Rep. Dan Lipinski, a moderate eight-term Democratic congressman from Illinois, lost his primary on Tuesday to progressive challenger Marie Newman.

Newman, a business consultant and founder of an anti-bullying nonprofit, narrowly lost to Lipinski in a 2018 primary in a suburban Chicago district by about 2 points.

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.

Three states are voting Tuesday in the Democratic presidential primary: Arizona, Florida and Illinois. Ohio suspended its primary. Follow NPR's live coverage with updates on the ground, news from the candidates, analysis and results.

So much has changed since the last round of primaries just a week ago. Coronavirus is dominating everything, and elections are on the back burner.

Some states have postponed their primaries over coronavirus concerns, and officials in Ohio, which is one of the four big states that was supposed to vote Tuesday, have suspended in-person voting.

After intense legal wrangling, Ohio postponed its Tuesday primary election just hours before polls were set to open.

Early Tuesday morning, the state Supreme Court denied a judge's attempt to let the primary continue after Gov. Mike DeWine had asked the court to delay the primary until June 2 because of the coronavirus outbreak.
