The controversy over the succession of the late Supreme Federal Judge Ruth Bader Ginsburg becomes an election issue in the USA.
Democratic presidential candidate Joe Biden reiterated his call for the vacant post in the influential Supreme Courterst to be filled by the winner of the November 3 presidential election.
Biden appealed to the Republican senators, "Please follow your conscience. Do not vote for someone nominated in these circumstances."
The Democratic candidate himself was in the Senate from 1973 to 2009 and has known many of today's members for a long time.
"Pushing through that Senate nomination would be using brute force political violence," Biden said.
"If I win the election, President Trump's nomination should be withdrawn," said the Democratic presidential candidate in a speech in Philadelphia.
The former Vice President is currently ahead of Trump in the polls.
Two Republicans want to vote on new judges only after the election
In the meantime, two Republican senators have spoken out against a vote on the post of judge so shortly before the presidential election.
Senator Lisa Murkowski from Alaska announced that she would not support a Senate vote on Ginsburg's successor "so close to the election".
The Republican Senator Susan Collins from Maine had previously opposed the quick vote requested by Trump.
Both senators belong to the moderate party wing of the Republicans.
In view of the narrow Senate majority of the Republicans, the declarations by Murkowski and Collins mean that Trump will probably not be able to enforce the quick replacement in the Supreme Court with only two other Republican dissenters.
According to observers, Senators Mitt Romney from Utah and Chuck Grassley from Iowa could also speak out against a quick replacement in the Supreme Court.
Other important Republican senators, such as Martha McSally from Arizona, Kelly Loeffler from Georgia and Thom Tillis from North Carolina, have already supported Trump and voted for a short-term vote.
Biden criticized the President of the Republic in the Senate, Mitch McConnell, for having announced that Ginsburg would vote on her successor "in the hour after the announcement of death".
McConnell had stated that he would not refuse to vote on the Ginsburg successor before the election - in a departure from his own earlier behavior: In 2016, over ten months before the presidential election, McConnell had the nomination process for a successor proposed by then President Barack Obama deceased Conservative judges blocked.
Obama's recruitment proposal failed - and shortly after he replaced Obama as president in early 2017, Trump reappointed a conservative judge for the vacant position at the Supreme Court.
Amy Coney Barrett is considered the most likely candidate
Ruth Bader Ginsburg died of cancer on Friday at the age of 87.
She was one of four remaining left-wing liberal judges on the Supreme Court.
Shortly before her death, she had expressed the wish that she "would not be replaced until a new president was installed."
But US President Donald Trump called the arrangement of her successor an "obligation without delay" and announced that he would make a choice "very soon", which would "most likely" be a woman.
District judge Amy Coney Barrett from Chicago is considered the most likely candidate, according to media reports.
She is known as a clear anti-abortionist - a central issue for conservatives in the United States.
The Democratic minority leader in the US Senate, Chuck Schumer, was critical of Barrett: "It stands for everything that Ruth Bader Ginsburg opposed. Someone with this philosophy does not belong in the court."
In addition to Barrett, the 52-year-old judge Barbara Lagoa is also considered a promising candidate.
She comes from Florida and thus from a state where the outcome of the upcoming presidential election could be decided.
With the successor to Ginsburg, President Trump wants to generate new enthusiasm among Republican sympathizers in his election campaign, which has so far centered heavily on the motto "law and order".
"We will occupy this seat," he announced to the cheers of his supporters at a campaign appearance in Fayetteville, North Carolina over the weekend.
"Take the seat! Take the seat!" The crowd shouted repeatedly in chants.
Democrats consider expanding Supreme Court
At the same time, the Democrats are preparing for Ginsburg's post to be filled before the election, thus cementing the conservative majority in the Supreme Court for decades. So there is the idea of enlarging the Supreme Court and allocating the new seats to liberal judges.
"We have to win the majority in the Senate first," said the democratic minority leader Schumer on Sunday.
Should that succeed, the Democrats would keep all options open. The Republicans currently have a majority of 53 of the 100 seats in the chamber.
Along with the presidential election, over 35 Senate seats will be voted on this year.
Of these, 23 are currently occupied by Republicans and twelve by Democrats.
Schumert rallied in New York with young congresswoman Alexandria Ocasio-Cortez.
She called for all available options to be used to prevent a quick replacement in the Supreme Court.
Ocasio-Cortez is particularly popular with young voters, who are likely to have a strong focus on issues such as women's and civil rights.
Ginsburg had advocated the importance of these topics all his life.
Her death on Friday mobilized supporters of the Democrats: on the ActBlue donation platform alone, more than $ 100 million was raised for the party's election campaign and political campaigns over the weekend.
The composition of the supreme court in the USA is of the highest political importance.
Because of the country's strong polarization, the Supreme Court often has the final say on key issues ranging from abortion to gun ownership and the death penalty.
The judges are appointed for life by the President with the majority approval of the Senate.
This means that presidents can still have an influence on political life in the country decades after their term of office.
