Reply #8: It's a long-standing custom for "formers" to attend

The logic, is that even though they may be from different parties/eras, the transition/transfer of power is a peaceful and even celebratory event. The thing that would be the hardest, is when the defeated candidates are "obliged" to go so the show of "no hard feelings" prevails..

As creepy as it seems, it's better than the way some "former" leaders are treated. Some are under virtual house-arrest...or worse when their term "expires"..
