It is up to you to answer your own question if you are to be fair to Roy Moore. You have inferred repeatedly that it is because of some character flaw in him that certain pastors have not rallied to his cause.
Quit beating around the bush and just say what you think!
This is not about public display of the Ten Commandments --- it is about Moore and his ambitions.
With his alliances you might begin to see why pastors might be leary aligning themselves with Moore.....
