While I agree with the second response that Muslims and Arabs are more marginalized, I do think that a Jewish president would be criticized on the basis of his Judaism. Kennedy was criticized as a Catholic, and Romney has had to bear the burden of attacks on his Mormonism. I see nothing to suggest that this would not be a problem for a Jewish president, assuming one would be electable in the first place. Also, there is so much rhetoric about this being a Christian country, and those who would like to see prayer returned to school are most definitely not advocating for anything but Christian prayer. This marginalizes Jews, Muslims, Hindus, Buddhists, Sikhs, and any other religion that is not Christian.
