14 states and one U.S. territory will vote in Democratic primary contests today, rocketing the total number of pledged delegates allotted from 5% to 38%.

Why it matters: With a total of 1,357 delegates up for grabs, Super Tuesday has the potential to definitively shape the remaining three months of primaries by giving one candidate an insurmountable lead. 1,991 delegates are needed to clinch the nomination at the Democratic National Convention in July.

Timing: Polls close throughout the night, beginning with Vermont and Virginia at 7 p.m. ET and culminating with delegate-rich California at 11 pm ET.

  • Yes, but: We won't know the full results for days, especially in large states like California that accept mail-in ballots postmarked no later than March 3.

On the ballot: Sen. Bernie Sanders, former Vice President Joe Biden, former New York Mayor Mike Bloomberg, Sen. Elizabeth Warren, and Rep. Tulsi Gabbard.

  • Worth noting: Pete Buttigieg, Sen. Amy Klobuchar, Tom Steyer, Julián Castro, and Sen. Cory Booker dropped out after the registration deadline, meaning they'll still appear on the ballot in Super Tuesday states.
  • Millions of ballots have already been cast in early voting, and most states don't allow voters to change their vote even if their candidate has dropped out.

Harvard and MIT on Wednesday filed a lawsuit against the Department of Homeland Security to block federal guidance that would largely bar foreign college students from taking classes if their universities move classes entirely online in the fall.

The big picture: Colleges, which often rely heavily on tuition from international students, face a unique challenge to safely get students back to class during the coronavirus pandemic. Some elite institutions, like Harvard, have already made the decision to go virtual.

Facebook auditors say it's failing on civil rights

The findings from a new civil rights audit commissioned and released by Facebook show that the tech giant repeatedly failed to address issues of hatred, bigotry and manipulation on its platform.

Why it matters: The report comes as Facebook confronts a growing advertiser boycott and criticism for prioritizing freedom of speech over limiting misinformation and protecting users targeted by hate speech.
