Detroit's clashes on Tuesday and Wednesday evenings, each containing ten candidates, mark the biggest moment of the White House campaign to date and will fuel the storylines of the first heated debates in June.
The location of the debates – in the battlefield state of Michigan – is a reminder of the task that the future Democratic candidate will face in November 2020. The once-blue bastion fell to Trump in 2016 and belongs to the Midwest battlegrounds where Democrats must reclaim working-class votes to claim the White House.
But before Biden and Harris meet again, Tuesday's Democratic Party base battle will be in the limelight as Sen. Elizabeth Warren faces Sen. Bernie Sanders, who has done more than anyone else Revive the Left but there is a danger that the Massachusetts senator outshines them.
The two progressive icons have largely avoided direct confrontation in the election campaign. And it may be that both at this early stage of the race have more incentives to differentiate themselves against more centrist democrats who both consider them too business friendly than trying to punch holes in each other's campaigns.
While they often line up In politics, Warren and Sanders differ in tone. The Massachusetts senator has rejected the "Democratic Socialist" label, which her colleague in Vermont has accepted and rated by Trump as extreme.
"I can only tell you what I believe, and that's an enormous amount to gain from the markets," she said, though she stated in her comment that the markets must have rules.
Tuesday The nightly debate could also be an opportunity for a centrist candidate like Montana Gov. Steve Bullock making his debut on the stage of the Democrats, or Minnesota Sen. Amy Klobuchar to stand up to the ultra-progressives. Right now, the temperate track looks like he's currently blocked out with Biden ̵
The first vote in the Democratic nomination race is more than half a year away. However, with the qualification criteria for the next debate in September doubling, outsiders are facing a moment of upheaval and have every incentive to locate top candidates for creating a viral television moment.
This Week's Contests It's also the first time that Democratic voters have seen their candidates together since Trump's attacks on democratic minority legislators channeled his 2020 hand.
The president has shown that he is ready to win racist issues to fuel his base, a factor that will influence a Democratic competition with racially diverse candidates.
Trump, keeping his fingers crossed for tweeting, is likely to topple when the Democratic candidates accept "The Squad" – four lawmakers he attacked racially when he said they should "go home" – though all four US citizens are.
He has made it clear that he wants to use the four women of color, to whom he accuses, they would like to use anti-American feelings, as an emblem for the entire demo cratic party.
But gun control, as promised by the Democrats to reverse Trump's hardline border strategies, is a topic that can provide opportunities for both the president and his enemies.
Biden vs. Harris
The eagerly awaited clash between the two prime-time debates is the rematch between Biden and Harris.
The former vice president looked shocked and unprepared when Harris challenged him about his opposition to the opposition to state-run buses in the 1970s for the integration of schools.
Biden's weak response to Harris's attack has worried some voters that his age is a responsibility. It also threatened to undermine his claim that he was the best Democrat who could take on Trump – a fierce debater.
Any candidate can have a bad debate. But Biden can not afford another.
Brett O & # 39; Donnell, a former debating coach for Republican campaigns, said Biden needed to make tactical adjustments.
"I think Joe Biden needs to be an effective counterattack, you know, if you're the front runner, you do not want to make contact," O & # 39; Donnell told CNN's Poppy Harlow.
"The principle is not to do any harm, but at the same time you do not want to appear as passive as in the last debate."
Biden's aides have told CNN that former Senator from Delaware will do so. Aggressive on Wednesday.
"He will not allow his file to be gunned," one official said. "He will not meet any of the candidates sitting down."
Nevertheless, the initial panic of some Democrats over the front runner seems to have subsided after the first debate.
So far Harris seemed to be less secure in spontaneous situations than in implementing precooked strategies in a debate. For example, it seemed to be turning several times into a key issue for the Democrats – how to improve the US healthcare system.
On Monday, Harris released a "Medicare for All" plan that maintains a role for individuals insurance in an apparent attempt to span the left and centrist wings of the Democratic Party.
The Fight for the Progressive Left
Four years ago, Sander's progressive territory dominated the democratic presidential race in his ultimately unsuccessful attempt to defeat former Secretary of State Hillary Clinton.
This time he sees things more crowded.
Sanders and Warren closely agree in the recent early national and state polls, suggesting that they are currently splitting up support from the most progressive activists.
The danger to Sanders now is that Warren, with her multiple plans and broader appeal, leaves the Vermont Senate far behind and inherits the move he has done so much for.
So he could swing on Tuesday Warren knows that it will not be enough to dominate the left – after all, in 2016 he failed to win Sanders.
Your performance is being watched See if she can deal with moderate voters and African Americans – two other crucial blocs of the Democratic Coalition.
Given the presence of Warren and Sanders, the first debate on Tuesday could also reveal the ideological gap in the Democratic Party. Bullock and former Colorado governor John Hickenlooper were critical of the party's development and could lead the way.
"I think as Democrats we have to be aware that we are not socialists," said Hickenlooper "CNN Tonight" earlier this month.
"I know we are not, but in many cases, these big, expansive solutions to some of America's annoying problems are pushing people away," Hickenlooper said.
"To say that in four years' time we will cancel all private insurance, ask 180 million Americans to give up their private insurance – I do not think that's realistic and I think that will not win elections."
Other outsiders need candidates big nights to keep their campaigns alive.
Former Texan MP Beto O'Rourke, who narrowly led Republican senator Ted Cruz through the Senate race in 2018, has to restore his luster. Former Minister of Housing and Urban Development, Julian Castro, was strong in his first debate – but he did not see a hoped-for vote.
Other candidates, such as New York Senator Kirsten Gillibrand, Colorado Senator Michael Bennet, New York City Mayor Bill de Blasio, and Washington Governor Jay Inslee, know they have the time running out to the top of the list penetrate.
Others, such as businessman Andrew Yang and self-help guru Marianne Williamson, face the problem of achieving the same time.
