I have been only half following this. I know that the Republican candidate Roy Moore, as a judge some years ago erected the Ten Commandments outside his courthouse and refused to remove them when ordered by a higher court, on the grounds that the US constitution enforces separation of religion from the state. That on its own is more than enough reason for me to hope the guy would never be elected dog catcher.
However the major controversy surrounding him seems to be that he has a sexual interest in young girls. Now if true this should clearly be a reason for him not to be elected, nor indeed chosen as a candidate by and respectable political party. However none of the accusations I have seen reported seem very substantial, and they all appear to have involved events that occurred over 30 years ago.
Maybe I have missed something, but why do so many consider him anathema. I don't think its the fact that he is a religious nut, that would do it for me, but it doesn't seem to be the main objection to him.
