The campaign may include anti-Trump demonstrations and protests at the Republican National Convention.
Democrat strategists and supporters of presidential frontrunner Hillary Clinton have decided to launch an "orchestrated" campaign against potential Republican rival Donald Trump, even as the controversial billionaire is facing a revolt from his own party leadership.
22 liberal groups have united behind a campaign to stop the 69-year-old real estate magnate with a plan that includes anti-Trump demonstrations, possibly including protests at the Republican National Convention this summer in Cleveland, and marches in major cities.
"Donald Trump's candidacy is a threat to the America we love, and we must respond to him and what he is stoking as such - with a nonviolent movement grounded in love and community that ensures that he never comes anywhere near the White House, and perhaps even more importantly, makes clear to every other politician and every person in the United States that racist demagoguery is a dead-end political strategy that most Americans reject," the groups said in an open joint letter.
The groups also include several Indian-Americans - Deepak Bhargava, Centre for Community Change Action; Sarita Gupta from Jobs With Justice, and Miya Yoshitani from APEN Action.
"We are calling for a massive nonviolent mobilisation of working people, students, immigrants, children of immigrants, great-great-grandchildren of immigrants, people of colour and white people, the unemployed and under-employed, people of faith, retirees, veterans, women, and men - anyone who opposes bigotry and hate and loves freedom and justice - to stand up to Trump's bullying and bigotry," the letter said.
"So far, Trump has bounced around the country speaking to people in these stadium rallies, and we haven't seen massive marches outside the rallies," Ben Wikler, Washington director for Moveon.org, said.
Wikler is leading the coalition and backs Senator Bernie Sanders, the sole Democratic presidential rival of Clinton.
The Trump Campaign, however, asserted that such a move would backfire, citing the fate of Republican candidates who had attacked Trump. "What you find with Donald Trump is he's a counter- puncher. Someone punches him and he punches back, and he punches back much harder. That's what the Republican field has come to realise," Corey Lewandowski, the Trump campaign manager, said. Both Clinton and Trump are leading their respective parties in delegate count and are most likely headed for a face-off in the November 8 presidential elections.
