It is interesting that religious significance is being attributed to both Barack Obama and Sarah Palin by individuals and communities that are very different, but have in common a tendency towards extremism.
On the other hand, Louis Farrakhan’s Messianic view of Barack Obama is being highlighted by conservative sources like Uncommon Descent:
It seems advisable to not jump to conclusions about either candidate interpreting their role in the same way that some religious communities are. I suspect that most Americans, even the devoutly religious, would not like to vote for either a theocrat or someone with a Messiah complex. And so if the views expressed by these preachers could be attributed to the candidates in question, then there’s a reasonable chance that Ross Perot might win by write-in vote.
