Graham, who tethered himself to former President Donald Trump, is among a handful of Republicans declaring their willingness to break party lines and vote for the yet-to-be-announced White House choice to replace retiring Justice Stephen Breyer.

Whether Graham or any Republican ends up backing Biden’s eventual nominee in the 50-50 Senate will be a new test for the president’s long stated and rarely achieved ambitions to see Washington embrace a more bipartisan approach after the bitterness of the Trump era…

While Graham has supported many Democratic judicial nominees, he also has hewed to the party line in two critical moments — the first in blocking now-Attorney General Merrick Garland from even getting a hearing when he was nominated for the Supreme Court during the final year of Barack Obama’s presidency. Then, four years later, he did an an about-face as chairman of the Judiciary Committee and shepherded Barrett’s nomination through just days before the presidential election.
