You know what?? I love Pres Bush, but that is NOT an excuse...as much as people want "the Pres has to be able to..." this is one of those things: buck it up! That is so ridiculous, and lame, to think he would be too emotionally "overwrought" to carry on in a debate. Heavens! If that's the case, what happens when his doggie dies & he has to make a crucial decision. Gimme a break.
