The US Constitutional crisis
Robert Kagan has a brilliant opinion piece in the Washington Post on America's Constitutional Crisis.
I can't think of another major western democracy where election results are challenged as regularly as they are in the United States.
I also can't think of one where the regional responsibility for elections has created so many conflicting standards over what should be a straightforward process (voter ID, address confirmation, poll management, vote counting, etc.).
The United States has been living this most famously since the 2000 Florida vote recount, which illustrated exactly why the system was broken and needed to be fixed, and most recently since Donald Trump invented the Great Steal.
That's been a 20-year process with no improvement: only deterioration.
The next steps in the process are fairly logical, and Kagan does an excellent job in summarising them.
