First woman to accepted Democratic nomination for chairman will lay out the stark selection facing American voters one night after Obama electrified convention

Hillary Clinton will declare a moment of reckoning for America on Thursday night when she becomes the first woman to formally accept the Democratic presidential nomination.

In a speech due to be introduced by her daughter Chelsea and after performances by Carole King and Katy Perry, the former secretary of state takes the stage in Philadelphia with the weight of world expectations on her shoulders.

Powerful forces are threatening to pull us apart, she will say, according to remarks released in advance by her campaign. Bonds of trust and respect are fraying. And just as with our founders there are no guarantees. Its truly is up to us. We have to decide whether were going to work together so we can all rise together.

She will go on to explain how she will empower all Americans to live better lives. My primary mission as chairman will be to create more possibility and more good tasks with rising wages right here in the United States. From my first day in office to my last. Especially in places that for too long have been left out and left with. From our inner cities to our small towns, Indian Country to Coal Country. From the industrial Midwest to the Mississippi Delta to the Rio Grande Valley.

On national security she tells Americans face a stark choice. Anyone reading the news can see the threats and turbulence we face. From Baghdad and Kabul, to Nice and Paris and Brussels, to San Bernardino and Orlando, were dealing with determined foes that must be defeated. No wonder people are anxious and looking for reassurance – looking for steady leadership, an implied criticism of her unpredictable Republican opponent Donald Trump.

Echoing a campaign theme and the slogan of Democratic signs often waved throughout the coming week in Philadelphia, she will say: Every generation of Americans has come together to stimulate our country freer, fairer, and stronger. None of us can do it alone. Thats why we are stronger together.

Fifty-two countries have had a female head of state already and Clinton would join Britains second female prime minister, Theresa May, and German chancellor Angela Merkel at the top table of elected leaders were she to win the US general election in November.

But Clinton has fallen behind Trump in opinion polls after a Republican convention last week that painted a dark vision of a world that merely he could make safe again.

Initial division among Democrats has been overcome through barnstorming speeches from two presidents, another first lady and a vice-president, who created the stakes for their candidate by warning that her foe posed an unprecedented menace to American diplomacy.

Tonight in her speech Hillary is going to stitch together each of these themes and talk about how such elections is genuinely a few moments of reckoning for the voter, Clintons campaign manager Robby Mook told reporters in advance of the long-awaited speech. Are we going to succumb to some powerful forces that are tearing at our social fabric or are we going to come together to solve these problems to build a nation that works for everyone?

Aides are alleviated that, despite fractious scenes involving those in favour of Clintons former rival Bernie Sanders at the beginning of the week, the Democratic convention in Philadelphia has for once pulled bigger television audiences than Trump. They hope Clintons speech will provide her with an even bigger ricochet as she heads off on a bus tour of rustbelt battlegrounds this weekend.

They also hope her speech will exploit fear among Republican about Trumps growing flirtation with and support from Russias Vladimir Putin.

This if the first time in modern history that weve presumably had a foreign power seek to engage in and influence in our election, said Clinton communications director Jennifer Palmieri on Thursday, referring to the ongoing speculation that Russia was behind the hack of Democratic emails that led to the abdication of party chair Debbie Wasserman Schultz.

Touting itself as the party of inclusiveness and diversity, Democrat have welcomed to the stage a number of Republican and independent legislators in an overt bid to appeal to moderate and conservative voters disillusioned by Clintons bellicose GOP rival.

What we heard in Cleveland last week wasnt particularly Republican and it sure wasnt conservative, Barack Obama told the convention on Wednesday night. What we heard was a deeply pessimistic vision of a country where we turn against each other, and turn away from the nations of the world. There were no serious solutions to pressing problems merely the fanning of bitternes, and blame, and indignation, and hate.
