I agree for the most part.
I'd like some Amendments thrown out-- Income tax and popular election of senators. These were bad.
I'd like Second Amendment to specifically block all gun control at all government levels. Original wording (apparently) wasn't clear enough.
I'd like Natural Born Citizen to be explicitly defined as born on US soil, to two parents both of whom were US citizens at time of child's birth.
There are some additions I would like, but I think it's a bad idea to create a "wish list" of neat things to throw into the document. I'd like the original document tightened, and that's about it.
+1 on everything you said.
