This week was one characterized by major election headlines.

Ahead of Super Tuesday, where 34% of the total delegates were awarded, both Sen. Amy Klobuchar and former South Bend, Ind., Mayor Pete Buttigieg announced the end of their 2020 presidential bids, along with billionaire Tom Steyer.

Klobuchar and Buttigieg’s decisions came as fear grew that an overcrowded centrist lane could divide moderate voters and pave the way for Sen. Bernie Sanders to win the Democratic nomination. Both candidates announced their support for former Vice President Joe Biden. 

Heading in to Super Tuesday with increased momentum, Biden won 10 of the 14 states up for grabs. While Mr. Sanders took Colorado, Utah, Vermont and probably California. (Mr. Sanders leads there, but the race has not been called.) California is a big deal — it awards far more delegates than any other state — but that doesn’t change the reality coming out of Super Tuesday: While the race certainly isn’t over, Mr. Biden is now the front-runner. As the delegate count now stands, Biden leads with 610, followed by Sanders with 541.

President Trump and Mike Pence continue to update the nation on the coronavirus outbreak.
