The Supreme Court has 9 justices, including a designated chief justice. The number of justices is not set by the constitution, but it’s been nine for the last 150+ years.
The Democrats are dissatisfied with the “balance” of the court, and are threatening that if they gain the presidency and control of the Senate, they will let Biden select an unspecified number of additional justices.
The idea is they can change future court rulings by simply appointing a lot of people amenable to construing the constitution according to their liking. This has been openly threatened by Senator Chuck Schumer recently, and by VP candidate Harris earlier in the campaign.
Though the idea of using court packing has support on the far left, it tends to scare more moderate voters even on the Democrat leaning side. As a result, neither Biden nor Harris want to be pinned to a firm answer because either stance would alienate a portion of potential voters.
In the recent debates, both Harris and Biden refused to answer whether they’d support court packing. Biden later said “You’ll know my position after the election.”
Pressed again by a local reporter who said it was a big issue with his readers, and “don’t they have a right to know?”… Biden said “No, they don’t….”
He then elaborated with extraneous drivel and accusations, but what I heard was the same thing he angrily told the 2nd amendment supporter in the hard hat at a campaign stop…
“I don’t work for you!”
