The revolving door in Malaysian politics is worrisome.

The country has had three prime ministers in three years. More troubling still is the return, in the last spin, of the old guard — the United Malays National Organization (UMNO) — in the person of Ismail Sabri Yaakob, sworn in as Malaysia's ninth prime minister last weekend.

UMNO lost power after six decades in office when a multibillion-dollar scandal ensnared its leading figures, including Prime Minister Najib Razak. The return of UMNO without the endorsement of voters is a cynical and disillusioning moment for Malaysia. Overturning the verdict of the voters in a democracy is always dangerous.
