US Democratic presidential candidate Joe Biden has accused President Donald Trump of wanting to overturn the health care reform known as Obamacare by quickly filling the vacant Supreme Court magistrate's post.

Trump and the Republican Party wanted to confirm incumbent nominee Amy Coney Barrett as the successor to the late Judge Ruth Bader Ginsburg ahead of the November 3rd election, "because they see a chance to see Barack Obama's healthcare reform on its way out the door tip, "said Biden.

Trump had nominated the ultra-conservative federal judge Barrett for the Supreme Court on Saturday.

The Catholic is known as a strict anti-abortionist and has campaigned for the right to gun ownership in the past.

She also took action against Obamacare.

Your nomination has yet to be confirmed by the Senate, where Trump's Republicans have a majority.

But they could lose that in November: Not only will the President be elected, but also the House of Representatives and a third of the Senate.

Biden again asked the Senate to decide on the personnel only after the election.

"Never before in the history of our country has a constitutional judge been nominated and installed while a presidential election is underway," said the former vice-president.

Voting has already started in some countries where voting is allowed before the official date.

Trump, on the other hand, said in a television interview that there were no problems with appointing posts before the election.

"We have plenty of time."

Democrats want to prevent a conservatively dominated court

The occupation of the Supreme Court is of great political importance in the United States.

The judges are appointed for life.

Through their nominations, presidents can shape US politics for decades.

Because of the strong polarization of the country and the increasing blockades caused by the tensions between Republicans and Democrats, the Constitutional Court is also often the last resort to rule on particularly contentious issues such as the right to abortion or the health reform of Trump's predecessor in office. 

Presidents therefore often try to nominate judges who lean politically in the direction of their party.

Should Barrett be approved by the Senate, six of the nine posts would be held by Conservatives.

The Democrats want to prevent that.

They rely on a similar case at the end of Obama's term of office: in 2016, the Senate, which was already dominated by the Republican regime at the time, refused to confirm a judge he had nominated on the grounds that shortly before the end of his second term in office, he had no mandate for the appointment.

The US president said she was "extremely qualified for the job".
