Chaos:
1) Moore campaigns for the office of Chief Justice. One of his slogans is "The Ten Commandments Judge," referencing the plaque he used to hang in his courtroom - which was deemed constitutional.
2) Moore is elected Chief Justice.
3) Moore foregoes the plaque for a two-ton granite monument, which naturally must be placed front-and-center in the rotunda in the middle of the night.
Presumably, you know the rest.
See there? Chaos. Moore's public recognition came almost entirely from his battle to hang his plaque. Would he have been a good, fair Chief Justice? Maybe. Who knows? Ensuring fair, speedy trials quickly became secondary to politicizing his religion - and not just his religion, mind you, but a not-so-subtle reminder that his God was a pretty angry, demanding, wrathful god once upon a time.
So, in conclusion, electing justices at pretty much any level is a bad idea.
