You would seem to be off in your calculations about the letter. I haven't seen that 327 number elsewhere, but I'll take your word for it. However, you neglected to count the 100 Senators. There are a total of 536 Congressmen and Senators, not 436. So those who have signed represent 61% -- not 75%. Still nauseating, but nothing like the good old days, huh?
