So you say, but I think you'll be disappointed. Especially when the right realizes they may need support of the left in some areas to pass term limits. That's when the deal making begins, and you must know of the right's penchant for bending over backwards to give the left whatever they want. You know, because "bipartisanship".
An Article V Convention will NOT end the way supporters suggest. Be careful what you wish for.
