I didn't watch all the speeches but I do recall a few people saying "mr president". I wish Christie had given HUSSEIN a tongue lashing, I was looking forward to it. Ann Romney did mention something about being an American, I loved it! There's a transcript on line if you missed her speech. Here's her closing remark:
"I can't tell you what will happen over the next four years. But I can only stand here tonight as a wife and a mother and a grandmother, an American, and make you this solemn commitment. This man will not fail.
