LONDON - Voting has ended in Egypt's presidential election and, although the final results may not be known until Monday, nobody doubts its outcome: President Abdel-Fattah El-Sisi, who has been in power since 2013, is guaranteed to win another four-year term with a crushing majority.

But, in many respects, getting re-elected has always been his easiest problem; running Egypt, by far the Arab world's most populous nation, remains a much more difficult proposition.
