The process may be different but the pickings for delegates and to chair a convention today could not come close to the men who forged the constitution.....
It's funny how those who want a Constitutional Convention say it's not about getting another Constitution -- but -- from the people I see who would be involved in that sort of thing (just look around you... LOL ...) -- there's a lot of them who would rewrite the Constitution in a New York minute....
And with the Chief Justice of the Supreme Court, Warren Burger, saying that there would be no limitation that could stop delegates from doing that -- well... you get the picture...
I choose not to go the "nightmare route" with a Constitutional Convention -- and simply do the Constitutional Amendments the same way we've done them since right after the country was formed (with #11 through #27) -- a process that would work and has been shown to work.
Another concern is do they think they won’t be challenged from the get go? Let alone once they begin...even when ammendments are in the process there are all kinds of challenges...in probition they wanted to set a deadline and the deadline was challenged clear to the supreme court!!!
