Donald Trump's campaign has scored a propaganda victory over Joe Biden, trolling him with a website and Twitter account that match the name of his new Hispanic coalition.

When Biden's staff settled on the Latino outreach effort's name, they skipped a step in what has become standard public relations practice.

So while the former vice president was campaigning in Iowa and Pennsylvania, and announcing the launch of 'Todos Con Biden,' Team Trump was busy trolling him on www.TodosConBiden.com and @todosconbiden.

'Oops, Joe forgot about Latinos,' both pages say, in English and Spanish. 'Joe is all talk.'

Links there go to Trump's own Hispanic coalition, 'Latinos for Trump.'

Now the accounts trumpet anti-Biden messages

Biden launched his push on Tuesday with a video message, saying that 'Latinos have contributed so much to our country.'

'Whether you've been here for generations or whether you're a dreamer whose family arrived recently, you're part of the fabric of America. You're Americans,' he says in the brief clip.

On Twitter, the president's campaign mocked Biden for getting chummy with Venezuela's iron-fisted strongman in 2015 when he was VP.

'Joe Biden talks a big game now but was all smiles with Venezuelan dictator Nicolás Maduro just 4 years ago,' they tweeted. 'The best he could do was complement the dictator’s hair. Meanwhile, the Obama-Biden Administration blocked sanctions against Maduro.'

The Trump campaign told ABC News that buying the Internet domain cost a 'minimal' amount of money

'Latinos are thriving under President Trump and now thanks to the Biden camp, people can find out more about that success' at the website, a campaign spokeswoman said.

President Trump won barely one-quarter of the Hispanic vote in 2016

The Biden campaign called the power move 'no surprise' and blamed the president's team for 'childish antics.'

A spokeswoman said in a statement that they are eager to 'take attention away from this President's appalling record of separating families and using immigrants as scapegoats, fomenting hatred and white supremacy, and trying to take away health care from millions of Americans who need it.'

According to the U.S. Department of Labor's October 4 jobs report, there are more Hispanics in the American workforce than at any time since the government began keeping statistics.

Hillary Clinton captured 66 per cent of the Hispanic vote in 2016, a 5-point decline from Barack Obama's 2012 performance.

Trump's campaign attracted 28 per cent, a 1-point improvement on Mitt Romney's result four years earlier.
