Excerpt:
One of the interesting things about this debate is that Obama never mentioned Islam. He refused to say the word, "Islam", "Muslim" or "Islamic" in this third debate. He used the word "Terrorism" only once, while Romney used it twice.
Romney mentioned Islamic extremism several times, he used the word Jihadist and spoke briefly about the Muslim Brotherhood takeover of Egypt. Romney not only mentioned terrorism more often than Obama did, he tried to give specifics.
Obama usually makes a fetish of promoting his outreach to the Muslim world, avoided all mention of the religion, likely on advice from his prep team, which pushed him to take as strong a posture as possible.
