It won't be voted on because the educational institutions,the universities and NGOs in America have said that the American people won't accept it.
And look at the European Union constitution. They railroaded integration into Europe through trade, and now that its time for the people to confirm it, all their polls says the people are overwhelmingly against it.
I'd vote against any constitution as long as the EU constitution. It was written by lawyers to create centralized unaccountable power for bureaucrats. The US Constitution was written to be concise and nontechnical so that ordinary people could read and understand it. Unfortunately we have overeducated lawyers in the US who use deconstructionism to invent all sorts of extentions to the Constitution that have absolutely no basis in the Constitution's text.
