A Democrat who wants to become the next president refused to guarantee he would not replace the judiciary system with left-leaning judges.

Presidential candidate Joe Biden did not rule out an earlier Democratic Party threat to pack the U.S. Supreme Court with liberal justices if Amy Coney Barrett is appointed to the court’s Seventh Circuit.

“It depends on how this turns out—not how he wins but how it is handled, how it is handled,” he said in a video shared by Yahoo News. “There is a number of things that are going to be coming up, and there is going to be a lot of discussion about other alternatives as well.”

The Democratic presidential nominee believes there are many ways to address his dissatisfaction with President Donald Trump’s decision to choose Barrett instead of waiting until after the general election on Nov. 3.

One of the possible amendments involves increasing the maximum number of justices who serve on the Supreme Court from the present nine, enabling the Democrats to add more left-leaning judges and balance-out what is likely to become a six to three majority that favors conservatives.

Biden is now considering whether to change America’s most fundamental principles and precedents to serve his political agenda.

“One of the things Pete [Buttigieg] has suggested is—and a number of constitutional scholars have suggested as well—that there are at least four or five options that are available to determine whether or not you can change the way in which the court lifetime appointment takes place consistent, arguably, with the Constitution,” he said. “I am open to considering what happens from that point on.”

However, the incumbent president believes appointing Barrett to the Supreme Court is a “great decision,” especially for defending the lives of unborn babies who are at risk of being aborted by their mothers. The judge has been a vocal critic of the Roe v. Wade landmark ruling that legalized abortion back in 1973.

“That is why I chose her,” the president said, according to Reuters.

Senate Majority Leader Mitch McConnell (R-Ky.) has confirmed the GOP has enough support to confirm Barrett as the next Supreme Court justice. Her nomination is now expected to be brought to a vote in the full Senate on Oct. 23. At least 51 votes are needed to make her appointment final.

“We have the votes,” McConnell said, according to Bloomberg News.

If successful, the entire confirmation process will have ended in slightly more than 30 days since the president formally announced Barrett would replace the late Justice Ruth Bader Ginsburg.
