Several years ago, very shortly after 9/11, he and Laura went on a foreign trip. I can't remember where it was to, but he kept Laura VVVEEEERRRYYYY close to him throughout the trip. He was obviously very concerned for her safety.
Ohio, do you remember the details?
Your memory is right. They never got very far from each other.
You know that is probably the one thing that makes him unsure of the presidency, because it is putting his loved ones in danger. 9/11 brought that into focus, no American president is safe, but neither are their family members. I pray for his safety, but I pray more for his family's, because if anything happened to them it would kill him. He's a caring man and he would feel it deeply.
