The problem with democracy is figuring out how to keep The People from picking the wrong guy.
In the US, the safety valve is the Electoral College. If, in a race between Hitler and Santa Claus, The People choose Hitler. . .well, there’s nothing really preventing the Electoral College from electing Santa, instead.
That said, fear not the not-quite-as-yet-scheduled Palestinian election. Certain, hidden powers-that-be, both within and without the PA, will make sure The People don’t choose Arafat.
