I think Manchin and Sinema in the Senate will block this, like they have most of Biden's ideas. That would swing it against the Democrats

Laurence Tribe has been waiting his whole life to get on the court. It would have to be an interim appointment because he is so old . He may be worse than Bryer. 

Who would've guessed (sarcasm):

Biden honors Breyer, promises to nominate Black woman to replace him on Supreme Court

President Joe Biden and Justice Stephen Breyer made a joint appearance Thursday afternoon at the White House to announce Breyer's retirement from the Supreme Court, clearing the way for Biden to follow through on his campaign promise to nominate the first Black woman to the high court for his historic first pick.
"I'm here today to express the nation's gratitude to Justice Stephen Breyer for his remarkable career of public service, and his clear-eyed commitment to making our country's laws work for its people," Biden said.

Biden praised Breyer's career in public service, beginning in the United States Army as a teenager before he went on to serve in all three branches of government before he turned 40. He was nominated to the Supreme Court in 1994 by President Bill Clinton.

"He has patiently sought common ground and built consensus, seeking to bring the court together. I think he's a model public servant in a time of great division in this country," Biden said.
Turning to the vacancy Breyer will leave, Biden also reaffirmed his commitment to nominate the first Black woman to the Supreme Court, which he said was "long overdue."
"I will nominate someone with extraordinary qualifications, charity, experience and integrity. and that person will be the first Black woman ever nominated to the United States Supreme Court," he said.
