'We got this': American left galvanized by death of RBG

The death of Ruth Bader Ginsburg sounded a warning for American progressives, thousands of whom -- wracked with ever-deepening concern for the future -- gathered Saturday outside the Supreme Court to honor the late justice.

Under an autumnal sun, a constant stream of families and young people gathered in Washington -- just 45 days from the US presidential election -- to pay homage to the progressive icon, affectionately referred to as "RBG."

"Ruth, I didn't know you, but you affected my life in many ways," says one of many letters placed at the foot of the court building, among flowers, rainbow flags and Ginsburg bobblehead figurines.

Among the anonymous mourners, Democratic vice presidential candidate Kamala Harris winded her way discreetly to the front of the crowd.

"RBG was one of my pioneers, an icon, a fighter. She was a woman in every way," she told AFP, shielding herself from the September chill with a black hooded sweatshirt.

Harris's running mate and President Donald Trump's opponent, Joe Biden, has failed to drum up great enthusiasm among progressive voters, due to his centrist views and advanced age -- 77.

But Ginsburg's death, in an America already on edge, could well galvanize them to his side.

Wearing a rainbow headband, J. Ford Huffman, a gay man in his 70s, urged Democratic voters to "use the mourning period to energize ourselves" and make sure everyone votes on November 3.

The challenge will be to prevent the doyenne of the Supreme Court from being replaced with her ideological opposite, since Trump has pre-selected very conservative candidates.

Ginsburg made her name as a lawyer in the 1970s by winning several major court battles that brought down a series of laws that discriminated against women.

Nominated to the country's highest court in 1993, she spent her 27-year tenure there defending the rights of the LGBT community and immigrants, establishing herself unequivocally as a champion of the American left.

- 'Vulnerable' -

"Thank you for teaching us how to fight," Gina Eppolito wrote in chalk on the pavement outside the imposing white marble building in the US capital, a city known for its progressivism.

The mother of two 11-year-olds, Eppolito said it was a "very big concern" of hers that rights acquired during her generation -- particularly the right to abortion -- might not be passed on to her children.

With Ginsburg's death at age 87, the US Supreme Court could fall into the conservative camp for a long time.

"We are in an extremely vulnerable position," Eppolito said.

Pam Crescenzo, 60, couldn't hold back her tears as she spoke: "If the courts continue to tilt to the right, it's really going to be a difficult time to be a woman in America."

"Her body was not even cold last night that Mitch McConnell was already saying how they were going to push through Trump's nominee for the next Supreme Court justice," she said, referring to the Republican Senate majority leader.

Crescenzo, who came with her wife, said it was thanks to RBG that they had been able to get married.

To her right, a group of people read out a Hebrew prayer. Ginsburg was born to a Jewish family in New York and died on the eve of Rosh Hashanah, one of the most holy days in Judaism.

In a sign of the deep divisions in the United States, a man wearing a black suit came to the court -- to praise Trump. He was roundly booed away by the crowd.

Many of the young people there also wanted to thank Ginsburg and to promise they would take up her fight.

"We have a lot of work to do and a lot of fighting to do in the next 45 days," said Kiley Boland, 25, who clutched a book on Constitutional law under one arm.

"It's on us now. She can rest; we got this."
