At a Monday night campaign rally in Detroit on the eve of Michigan\u0026#039;s primary election, former Vice President Joe Biden called protesters drawing attention to his record on trade and climate policies supporters of his rival in contest for the Democratic Party\u0026#039;s presidential nomination, Sen. Bernie Sanders.\u0022The Bernie bros are here!\u0022 Biden declared in between urging the crowd to let the demonstrators go and reminding them that the rally wasn\u0026#039;t for President Donald Trump, whose campaign events leading up to the 2016 election featured some violent clashes between Trump protesters and supporters.\u0022This is what\u0026#039;s wrong with American politics,\u0022 Biden said. \u0022I\u0026#039;m not worried about it. It\u0026#039;s just a reflection of what\u0026#039;s wrong with American politics today... This is one of the things that Donald Trump has generated. This is not who we are. This is not who we are as a party. This is not who we are as a people. We got a lot of crazy folks around.\u0022The first group to interrupt Biden\u0026#039;s rally was protesting the North American Free Trade Agreement (NAFTA), the 1994 trade deal that Biden supported as U.S. senator representing Delaware. The demonstrators at the Detroit rally unfurled banners that read \u0022NAFTA Killed Our Jobs\u0022 and \u0022Biden Betrayed Workers.\u0022Protesters against NAFTA disrupted Joe Biden’s rally tonight in Detroit. Biden voted for NAFTA and other free trade deals. Bernie Sanders, who opposed NAFTA, spoke out against NAFTA during his campaign rallies in metro Detroit. Trump also opposed NAFTA. pic.twitter.com/3ooZ6jv64L\u0026mdash; Niraj Warikoo (@nwarikoo) March 10, 2020At tonight\u0026#39;s Biden rally in Detroit, workers raised two banners: \u0026quot;NAFTA Killed Our Jobs\u0026quot; and \u0026quot;Biden Betrayed Workers\u0026quot; pic.twitter.com/oCkVp3cAA4\u0026mdash; Eric Blanc (@_ericblanc) March 10, 2020\r\nIn recent television advertisements targeting Michigan and other March primary states, Sanders has highlighted Biden\u0026#039;s vote for NAFTA and broader trade record. The senator has also slammed Biden\u0026#039;s position on NAFTA and Permanent Normal Trade Relations with China in statements to the press.\u0022I vigorously opposed these agreements; I helped lead the opposition to these agreements,\u0022 Sanders said last week. \u0022Joe Biden supported those agreements. And that is a fundamental difference about our approach toward the trade union movement and towards the needs of working people.\u0022Shortly after the anti-NAFTA protest at Biden\u0026#039;s rally, climate demonstrators raised signs that read \u0022Green New Deal Now\u0022 and \u0022Green Jobs for All,\u0022 and waved a banner that read \u0022This Is an Emergency.\u0022But we can\u0026#039;t get there with Joe. @BernieSanders is the only candidate that is mobilizing young people to get out and vote in the primaries \u0026amp; will be able to do that again in Nov. to defeat Tr*mp.Biden is running on nostalgia, while Bernie is ready to take us into the future.— Sunrise Movement (@sunrisemvmt) March 10, 2020Last night we and @byp100 held Joe Biden accountable for his failure to embrace a bold climate agenda and for his history of supporting legislation that has hurt workers and vulnerable communities in the states of Michigan.We deserve better. pic.twitter.com/77CJW1NL4n— Sunrise Ann Arbor(@sunriseannarbor) March 10, 2020The demonstrators included activists with Michigan Student Power and local branches of Black Youth Project 100 (BYP100), the Sunrise Movement, and Democratic Socialists of America (DSA). On a national level, the latter two groups have endorsed Sanders.pic.twitter.com/EQak6LpVOg— Detroit DSA (@detroitdsa) March 10, 2020Shout out to all the young Black and brown folks knocking doors, making calls, and turning up in the streets to say #NoOnJoe! We’re fighting hard for a future where we are freer than we’ve ever been. https://t.co/VRs9XUlZ21— BYP100 (@byp100) March 10, 2020The rally was not the first time in the past week that Biden has seized on the \u0022Bernie Bro\u0022 narrative to dismiss his critics and Sanders supporters.At a fundraiser in Maryland Friday, the former vice president told his supporters that \u0022what we can\u0026#039;t let happen is let this primary become a negative bloodbath. I know I\u0026#039;m going to get a lot of suggestions on how to respond to what I suspect will be an increasingly negative campaign that the Bernie Brothers will run... We can\u0026#039;t tear this party apart and reelect Trump. We have to keep our eyes on the ball, in my view.\u0022The remarks sparked a swift response on social media, particularly from women and people of color backing Sanders, who used the hashtag #BernieBrothers and explained why they support the U.S. senator from Vermont. \u0022I\u0026#039;m a woman of color. I\u0026#039;m fighting for the kids in cages and the future of our planet,\u0022 tweeted author and activist Leela Daou. \u0022I stand with #NotMeUs. Does that make me one of the #BernieBrothers?\u0022The demonstrations at Biden\u0026#039;s rally came after Sunrise Movement executive director Varshini Prakash led a Sunday night conference call with members across the country.As VICE reported, \u0022Prakash called for a return to the \u0026#039;moral protests,\u0026#039; \u0026#039;strikes,\u0026#039; and \u0026#039;strategic disruption,\u0026#039; that catapulted the group from unknown advocates to a regular fixture in progressive politics,\u0022 such as multiple sit-ins at the Capitol Hill office of Democratic House Speaker Nancy Pelosi (Calif.) and the multi-day protest on the steps of the Democratic National Committee\u0026#039;s building in Washington, D.C..@VarshPrakash: ”We need to start thinking more creatively and outside the box about what we can do that goes beyond convincing one voter at a time.We need to think about how we can make 2020 a generational uprising for a Green New Deal.”https://t.co/1tjr3nviUz— Green New Deal Penguin (@GreenNewPenguin) March 9, 2020The Sunrise Movement, which advocates for a Green New Deal, is among the climate advocacy groups that have raised concerns about Biden\u0026#039;s plan to protect the planet.Although the campaign claims that \u0022Biden believes the Green New Deal is a crucial framework for meeting the climate challenges we face,\u0022 the former vice president has faced criticism for plagiarizing portions of his climate plan, particularly for lifting language about carbon capture and sequestration from a fossil fuel industry-backed group.Sanders scored more than the double points that Biden received on the Sunrise Movement\u0026#039;s climate scorecard, which was released in December 2019, before the group endorsed the Vermont senator for making \u0022it clear throughout his political career and in this campaign that he grasps the scale of the climate crisis, the urgency with which we must act to address it, and the opportunity we have in coming together to do so.\u0022Sanders also leads the climate scorecard maintained by Greenpeace USA, which has not endorsed a candidate. That assessment is based on each candidate\u0026#039;s commitment to fully phasing out fossil fuels and championing a Green New Deal that launched a just transition to a 100% renewable energy economy while creating millions of \u0022family-sustaining\u0022 jobs.
