>> Any court packing attempt today would require a President of demonic charisma to push it through Congress <<
Not so sure. I think it would only require 218 votes in the House, 50 votes plus the VP in the Senate, and a willing (even if passive) POTUS.
OK, let’s test your hypothesis: after Pres. Trump’s nominee is confirmed, watch to see if the ever loonier libs introduce bills to add additional justices to the Court to achieve what they will call “ideological balance”.
They don’t have to succeed for your theory to be proven correct. We heard calls to abolish the Electoral College after Trump’s victory, so Court-packing wouldn’t be considered extreme. If a Court-packing bill appears in the next session, then your case is made.
Except....FDR’s court-packing attempt failed eighty years ago in 1937. The New Deal was his baby and he pushed hard to get more seats on the Court.
Have there been any attempts since then? I don’t know.
