Dear Sen. Allen,
I hope you do not mind this letter at this time when you are facing issues about use of the word macaca in relation to someone following you on your recent campaign stop. You have tried to explain it every which way you can. Please allow me to suggest something new to you.
You have never been able to pronounce the name Virginia even though you have called it home for most of your adult life, you graduated from the University of Virginia and you once served as governor of Virginia. You have always pronounced it "Vahginia."
So, you have used the work macaca without knowing what it means. I would suggest a new defense. Try saying your inablity to pronounce words was the problem. You were trying to say "my car, car." This would clear up the matter for the umteenth time. It could also get you out of the problem.
