“It is unconstitutional and where would it end? “
There is no plausible argument that packing the court is unconstitutional.
If Congress and the president agree to 47 justices, it will be so.
It betrays constitutional ignorance to say otherwise.
The intent of the founders was not for each election to result in more justices to swing the court one way or another. Then again, I don’t think the founders intended for one district court judge to issue blanket proclamations blocking the actions of the executive branch either.
