Mitt's Religion Speech

What has 2,540 words but only uses the word "Mormon" once? That would be Mitt's religion speech. Did he have a good reason for not mentioning his specific faith more often? He actually mentioned Islam more than LDS. Are there specific tenets of his faith that some suspicious voters should not know about? The entire text of Romney's speech can be found here. Here is one paragraph that just confuses the hell out me.

"Freedom requires religion just as religion requires freedom. Freedom opens the windows of the soul so that man can discover his most profound beliefs and commune with God. Freedom and religion endure together, or perish alone.

Do you really have to have religion to be truly free? Romney had to convince evangelical Christians that he is just like them. At least he said he would swear his oath on a Bible rather than the Book of Mormon. That should satisfy some evangelical Christians.
