@mralancooper In Ireland, FWIW

The constitution can only be amended by the people in a referendum -- belongs to the people not politicians.

Idea of judges running for office is anathema. An independent judiciary makes its own appointments. Politics not part of it.

In addition

Political boundaries set independently (no gerrymandering)
State funding for parties w 2% of vote
Max €1,000 political donation
Proportional voting
No vote suppression

US overdue a rethink. We amend frequently.
