It is the one question that unites Americans when it comes to President Joe Biden.

Ask Democrats, Republicans or independents for their one-word summary of his legacy and they put aside their differences to answer almost unanimously: Nothing.

Those are the extraordinary results of an exclusive poll conducted for DailyMail.com by J.L. Partners.

Some 1,009 registered voters were asked for their brief description of the legacy of Biden, who leaves the White House on Monday at the age of 82 after four turbulent years.

When the results are arranged in a word cloud, the most common answer sticks out at the center. The next most popular answers are economy, inflation, and infrastructure, in a more encouraging nod to one of his landmark pieces of legislation.

Yet the same word, 'nothing' stands out when the responses are split by political persuasion.

For Democrats, the memory is softened by other words such as 'good,' 'stability,' and 'better.'

But as Biden prepares for a life outside politics for the first time in half a century, and plans for a presidential library and other elements of his legacy, it suggests at least the first draft of history is unlikely to be kind to him. 

And there is worse in other parts of the poll. 

When voters were asked whether they can remember a single Biden achievement, more than half say they cannot. Some 37 percent say they 'strongly' agree with the statement that they cannot name a single one.

Even Democrats struggle. More than a third said they could not name a single achievement.

The results echo an earlier poll, which found that voters ranked Biden as the least successful of recent president.

James Johnson, co-founder of J.L. Partners, said it was a diabolical 

'As far as public opinion is concerned, you have to squint to see even the echoes of a legacy—and even then people are more likely to remember it negatively,' he said.

'Biden's biggest achievements in office—such as legislation in Congress – are crowded out by the overriding view: That he was responsible for inflation, and that he was a mentally unwell Commander-in-Chief. 

'Perhaps the history books will be different, but in the minds of the public there's no legacy to be seen.'
