BAD MOVE!!! Islam has NO PART in this country!!
Having a muslim prayer at the convention will win Trump no new supporters, but it will serve to de-energize his existing supporters.
He had it right when he said ban on Muslim immigration. Stick to that.
Then I guess you missed Melania's speech last night where she said:
Donald intends to represent all the people, not just some of the people. That includes Christians and Jews and Muslims, it includes Hispanics and African-Americans and Asians, and the poor and the middle class. Throughout his career, Donald has successfully worked with people of many faiths and with many nations.
