The McCain campaign has forced me to rebut its advert that mockingly likens Barack Obama to Moses. This critique need not resort to religious doctrine: It is possible by presenting Moses as a literary figure.
Two things pop to mind: One, Moses split the Red Sea, while Obama has thus far managed only to split the Democratic party.
Also, Moses was a reluctant political leader. From the Jewish Publication Society translation of Exodus 3:11:
And Moses said unto God: 'Who am I, that I should go unto Pharaoh, and that I should bring forth the children of Israel out of Egypt?'
God had to goad him:
And He said: 'Certainly I will be with thee; and this shall be the token unto thee, that I have sent thee: when thou hast brought forth the people out of Egypt, ye shall serve God upon this mountain.'
and, several verses into their negotiations, offer him a loyal spokesman:
And the anger of the LORD was kindled against Moses, and He said: 'Is there not Aaron thy brother the Levite? I know that he can speak well. And also, behold, he cometh forth to meet thee; and when he seeth thee, he will be glad in his heart.
