Also looking at the photo, there are two writing styles on the paper itself. The top half is plain, with a mix words writting in caps and others not. Below it, it looks like it is in script (or Bush script). Maybe Bush (if this is Bush as Rick Wilking claims) is responding to someone elses not to him?
Also, the linewidth in the upper text is wider than the lower part. I don't think Bush stopped halfway through his note to sharpen his pencil and change his writing style.
Here's another example of Bush handwriting.
This example includes two printed capital letters that occur in the printed top portion of the note: "M" and "I". The "I" in the letter has the vertical crossing the top horizontal. In the note, it is the opposite--and the top and vertical don't even touch in the second "I". The "M" in the letter shows the middle point coming only halfway down. The note has the legs and middle in a line. Also, the "M" in the letter is much more angular than the rounded "M" in the note.
Also compare the note's "E"s in "NEED" with the capital "F" in "Freedom" in the Iraq note. The "E"s are wide-open at the top, but the cross parts of the "F" cross far over to the left.
