After Super Tuesday\u0026#039;s results made clear that the 2020 Democratic primary is now a two-candidate race between former Vice President Joe Biden and Sen. Bernie Sanders, progressives called for an end to divisive infighting and some urged Sen. Elizabeth Warren to join Sanders in a united front against the party\u0026#039;s deep-pocketed and organized establishment wing.\u0022I\u0026#039;m a Bernie supporter who builds with Warren supporters,\u0022 tweeted Varshini Prakash, executive director of the youth-led Sunrise Movement, which endorsed Sanders in January. \u0022This isn\u0026#039;t the time for infighting and vitriol. Let\u0026#039;s leverage our shared power to break through the wall of corporate media, win this primary, and defeat Trump. Let\u0026#039;s #BuildTogether.\u0022\u0022The obstacle in the way of a more progressive future for Americans isn\u0026#039;t Sanders, but the coalition forming around Biden. If Warren wants a righteous fight, this is it.\u0022 —Sarah Jones, New York MagazineIt was a call for progressive unity that others echoed both before and after Super Tuesday, which saw Biden win 10 of 14 states—including delegate-rich Texas—and take a narrow lead in pledged delegates. Sanders won four states, including California, the largest delegate prize of the night.With the #BuildTogether hashtag making the rounds among both Sanders and Warren supporters, journalist Sam Adler-Bell said the \u0022posts are quite obviously an effort to build goodwill between two support bases that absolutely must combine to defeat the corporate/billionaire wing of the party. I have no patience for anyone upset about it.\u0022Roger Lau, Warren\u0026#039;s campaign manager, sent an email to staffers Wednesday morning announcing that Warren is meeting with her team to \u0022assess the path forward\u0022 after she failed to place higher than third in any of the Super Tuesday states, including her home state of Massachusetts.\u0022This decision is in her hands,\u0022 wrote Lau, \u0022and it\u0026#039;s important that she has the time and space to consider what comes next.\u0022Sanders campaign manager Faiz Shakir echoed that sentiment in an interview with CNN ahead of Super Tuesday. \u0022She has been campaigning very hard, has raised a lot of money, and has earned a lot of votes,\u0022 Shakir said. \u0022She should be given the time and space to decide for herself about the future of her campaign.\u0022Lau\u0026#039;s announcement came shortly after billionaire businessman Michael Bloomberg dropped out of the presidential race Wednesday and immediately threw his support behind Biden, handing the former vice president an effectively bottomless source of financial support.Tim O\u0026#039;Brien, who served as a senior adviser to the Bloomberg campaign, said the former New York City mayor plans to put his resources \u0022in the broadest way possible behind Joe Biden\u0026#039;s candidacy.\u0022Investigative reporter Alex Kotch argued in a series of tweets that Bloomberg\u0026#039;s decision to support Biden only increases the importance of Warren\u0026#039;s next steps:Bloomberg is out and endorses Biden.I imagine we\u0026#039;ll hear from Warren later today or tomorrow. If she drops out \u0026amp; endorses Bernie, the race is on. Otherwise, hard to think it\u0026#039;s not a very rough road for Bernie.— Alex Kotch (@alexkotch) March 4, 2020It\u0026#039;s Biden vs. Bernie. It\u0026#039;s the establishment vs. the left. That\u0026#039;s it.— Alex Kotch (@alexkotch) March 4, 2020New York Magazine\u0026#039;s Sarah Jones wrote Monday that because the Democratic establishment and big-money donors are rapidly coalescing behind Biden, it is time for Warren to leave the presidential race and support Sanders for the Democratic nomination.\u0022For Warren\u0026#039;s supporters, this will be difficult to accept, and for good reason,\u0022 wrote Jones. \u0022The senator has spoken movingly of her working-class background, and introduced a slate of generous policies that represent long overdue corrections to corporate power. In debates, she can be fearsome. She is probably the first person to publicly humiliate Michael Bloomberg in years.\u0022But without a realistic path to the nomination, Jones added, \u0022it would be a catastrophic error in judgement for Warren to remain in the race till the convention.\u0022According to a national Quinnipiac poll released last month, 33% of Warren supporters say Sanders is their second choice for president—a number Jones argued could rise if Warren backs Sanders with a full-throated endorsement.\u0022If she can make the case for Sanders, she\u0026#039;ll help build a progressive front against a moneyed and well-organized moderate force,\u0022 Jones wrote. \u0022The time to do so is now. The obstacle in the way of a more progressive future for Americans isn\u0026#039;t Sanders, but the coalition forming around Biden. If Warren wants a righteous fight, this is it.\u0022Working people have few allies in the Senate; Elizabeth Warren is one of them. But she doesn\u0026#039;t have a realistic path to the nomination, and staying in the race could harm the progressive cause she espouses. https://t.co/OfVqDa9Y3V— Sarah Jones (@onesarahjones) March 2, 2020Author and activist Naomi Klein, who actively supports Sanders in the campaign, expanded the call for a united progressive front by saying not only Warren, but anyone with reach and power who remains willing to fight for bold and transformative change, should join hands at this critical moment:Biden benefited from a big show of unity. We need a supergroup of ppl who understand Biden is not up to it on a platform endorsing Sanders, #NotMeUs + pledging to help make it work. Our moment in history demands it.@ewarren @TomSteyer @JayInslee @AyannaPressley... add who else!— Naomi Klein (@NaomiAKlein) March 4, 2020After President Donald Trump on Wednesday morning fired off a tweet seemingly intended to sow further division among Sanders and Warren supporters, comedian and Medicare for All activist Rob Delaney responded that \u0022as with most ideas this suppurating wound of a person extrudes, it would be a good idea to do the exact opposite.\u0022\u0022I hope Sanders and Warren understand this and unite,\u0022 Delaney wrote.
