If we call for and get the convention, you forget that EVERY amendment is open for change. Not just the ones you want. There's a reason another convention hasn't been called for such a long time. Stupid people will want to change the first two amendments so that we don't have those anymore.
That is a slippery slope to start down. Once one piece is changed, or eradicated, they can all be changed or eradicated. Leave the Constitution alone and govern by it, removing all the extra laws and laws for laws and exceptions to following the laws instead
Turn all social programs, yes even education over to the states and let their people decide whether their tax dollars are making an impact. The federal government is suppose to be about protecting citizen's rights and defending this country not being a national ATM. "Promoting the general welfare" is about giving states the okay to move ahead on creating laws and fiscal matters, not providing welfare.
