Michelle Obama: ‘When they go low, we go high’

Michelle Obama cast the presidential race as one between a positive role model for children – in Hillary Clinton – and a damaging one – in Donald Trump – in the marquee speech on the Democratic National Convention’s opening night.

The first lady never mentioned Trump by name, but leveraging her popularity, she made a rare, if not unprecedented, foray into partisan politics to knock the Republican nominee.

Obama condemned “the hateful language that we hear from public figures on TV,” saying that “our motto is, when they go low, we go high.”

And in a shot at Trump’s “Make America Great Again” campaign slogan, Obama discussed raising her children in a White House that was built by slaves.

“Don’t let anyone tell you that this country isn’t great. This right now is the greatest country on earth,” the first lady said.

Obama electrified the crowd at the Wells Fargo Arena in Philadelphia, taking the stage just after 10 p.m. ET and – in a departure from the political attacks on display all day – making the case that, because of her character and temperament, Clinton is the role model she’d like her daughters to see in the Oval Office.

Even Trump, who Obama was implicitly criticizing, praised her remarks.

“I thought her delivery was excellent,” Trump told The Hollywood Reporter. “I thought she did a very good job. I liked her speech.”

It was a remarkable embrace of the prime-time stage for Obama, who was reluctant about the spotlight that came when her husband, then-Illinois Sen. Barack Obama, launched his presidential campaign against Clinton in 2007.

“To understand the journey she’s taken as a reluctant conscript on the public scene, to come here and command that stage the way she did tonight was extraordinary – and I think did for Hillary Clinton what no one else has done to this point,” said David Axelrod, a top Obama strategist on the 2008 campaign and now a CNN political commentator.

During her speech, Clinton ripped into Republican nominee Donald Trump for his convention pitch "I alone can fix it." She said: "He's forgetting every last one of us. Americans don't say: 'I alone can fix it.' We say: 'We'll fix it together.' "

Clinton acknowledges the crowd before her speech.

Clinton's husband, former U.S. President Bill Clinton, applauds along with their daughter, Chelsea.

Clinton is the first woman in U.S. history to lead the presidential ticket of a major political party. "It's true," she said in her speech, "I sweat the details of policy -- whether we're talking about the exact level of lead in the drinking water in Flint, Michigan; the number of mental health facilities in Iowa; or the cost of your prescription drugs. ... Because it's not just a detail if it's your kid, if it's your family. It's a big deal. And it should be a big deal to your President."

Clinton gives a thumbs-up to the crowd.

Donald Trump, you are asking Americans to trust you with our future. Let me ask you: Have you even read the U.S. Constitution? I will gladly lend you my copy."

"This year, in this election, I'm asking you to join me -- to reject cynicism, reject fear, to summon what's best in us; to elect Hillary Clinton as the next President of the United States, and show the world we still believe in the promise of this great nation," Obama said.

Obama told the crowd at the Wells Fargo Center that he is "more optimistic about the future of America than ever before." He contrasted it with the "pessimistic vision" of America he heard during the Republican convention last week. "There were no serious solutions to pressing problems -- just the fanning of resentment, and blame, and anger, and hate," he said.

Obama said Clinton is more ready than he was to become President. "For four years, I had a front-row seat to her intelligence, her judgment and her discipline," Obama said, referring to her stint as secretary of state.

The crowd welcomes Obama.

Clinton's running mate, Tim Kaine, waves to the crowd along with his wife, Anne Holton, after giving a speech on Wednesday.

That's what you're about. That's what Bernie Sanders is about. That's what Joe Biden is about. That's what Barack and Michelle Obama are about. And that's what Hillary Clinton is about."

U.S. Vice President Joe Biden also went after Trump, saying "this guy doesn't have a clue about the middle class -- not a clue. Actually, he has no clue, period."
