Biden Vs. Sanders Endorsements: Buttigieg, Klobuchar and Other High-Profile Support Ahead of Super Tuesday

Former U.S. Ambassador to the United Nations Susan Rice has publicly endorsed former Vice President Joe Biden in his run for the Oval Office. Biden has also picked up an endorsement from former presidential candidate Minnesota Senator Amy Klobuchar, who withdrew from the presidential race Monday and gave her support to Biden.

Former South Bend, Indiana Mayor Pete Buttigieg is also expected to give Biden his support after dropping out of the presidential race after the South Carolina primaries on Saturday.

Both Klobuchar and Buttigieg are expected to appear at a rally in Houston, Texas Monday to announce their endorsements.

National Democratic front runner Vermont Senator Bernie Sanders has also been garnering support for his campaign, receiving an endorsement from progressive political action committee Democracy for America [DFA].

This flurry of political endorsements comes the day before Super Tuesday, when Democratic voters from 14 states and the U.S. territory of American Samoa are expected to visit the polls to cast ballots for their favorite candidate. Over one-third of all delegates will be up for grabs during the Super Tuesday primaries.

Rice endorsed Biden on Twitter Monday, citing Biden's "deep compassion and decency" as one of the reasons for her decision.

"I'm proud to endorse @JoeBiden for President," Rice wrote. "Here he is comforting me on 1/14/17 just after my mother passed away. There is no one kinder, more empathetic and caring than @joebiden. He will lead America with the same deep compassion and decency."

Rice also called Biden "the strongest candidate to take on and defeat [President Donald] Trump" in a Twitter thread.

"Above all, @JoeBiden is a Democrat and the strongest candidate to take on and defeat Trump," Rice tweeted. "That's why Trump is so scared of Biden. Our fate as a nation depends on beating Trump. Nothing is more important, and now is not the time for risky bets or divisive revolutions."

DFA's endorsement of Sanders came after its membership gave him the majority vote.

"Breaking: @DFAaction is endorsing @BernieSanders for President in the 2020 fight for the Democratic nomination," the group tweeted. "Sanders earned the endorsement after receiving 79.3% in the DFA membership vote, easily passing our 67% supermajority threshold."

"The overwhelming support for Bernie we saw in our member vote should be a wake-up call to the broken, visionless, corporate Democratic establishment," wrote DFA Chair Charles Chamberlain in a statement Monday. "Americans want fundamental change in Washington, not a return to the status quo."

Newsweek reached out to both the Biden and Sanders campaigns but did not receive a response in time for publication.

Biden has been endorsed by a number of familiar politicians that voters may recognize while many of Sanders' endorsements come from labor and political organizations whose endorsements carry weight with millions of American voters.

Former Senate Majority Leader Harry Reid endorsed Biden Monday in a statement calling Biden "a much-needed stabilizing force following Trump's disastrous term, offering a positive and progressive alternative to Trump's dark vision of racism, xenophobia and policies built on cruelty and exclusion."

Biden has also been endorsed by some Democratic members of Congress such as California Representative Dianne Feinstein, Senator Tim Kaine of Virginia and Florida Representative Debbie Wasserman Schultz.

Sanders' more progressive policies have garnered him the endorsements of New York Representative Alexandria Ocasio-Cortez, Michigan Representative Rashida Tlaib and Representative Ilhan Omar of Minnesota.

Omar is expected to join Sanders onstage at a campaign rally Monday in St. Paul, Minnesota.

Sanders has also gained the support of a number of celebrities including actor Mark Ruffalo, musician Miley Cyrus and filmmaker Michael Moore.

Biden's celebrity supporters include actor Tom Hanks, director Rob Reiner and singer Cher.

Including Sanders and Biden, five Democratic presidential hopefuls remain in the race. Former New York City Mayor Michael Bloomberg, Massachusetts Senator Elizabeth Warren and Hawaii Representative Tulsi Gabbard are also running for the Democratic nomination.
