US President Joe Biden said Wednesday a presidential race against Donald Trump would convince him to run again for presidency in 2024.

"That would increase the prospect of running," Biden told ABC News.

When asked about whether he would stand for re-election, the 79-year-old Democrat responded that he would if he were in good health.

"Sure, why would I not run against Donald Trump if he were the nominee?" he added. 

Former US President Donald Trump continues to claim that his 2020 defeat to Biden was due to voter fraud and that the election was "stolen" from him.

It was under that pretext that Trump supporters stormed the US Capitol on January 6 as Congress was certifying Biden's presidential win.

Though Biden's second-in-command Kamala Harris was once considered his potential political successor, there are questions about her political future as rumors circulating through Washington say the president and vice president's relationship is not strong.

Harris, 57, seems to be struggling to find her place in the White House, where she has been charged with tackling particularly sensitive missions, such as minority voting rights and migration issues. 

Meanwhile, Trump has repeatedly hinted at another possible White House campaign but has yet to announce his plans.

It is noteworthy that a national poll conducted by the new Center for American Greatness revealed that 49% of respondents would vote for Trump if the US presidential election were held today, compared to 41% who would vote for Biden.
