There is nothing wrong with the constitution and amending it could go places you’d rather not want to consider.
Let’s just follow and enforce the damn thing instead of trying to interpret the finer nuances of what we think it should mean and we will be fine.
But that's the rub, isn't it? They have not enforced the damn thing since the new deal and we have no institution located in Washington DC, not the Congress, not the president, not the courts, who show the slightest inclination to enforce the damn thing. That institutional bias against enforcing the Constitution is endemic, it is inherent in Washington, and it cannot be cured in Washington, and probably cannot be cured by conventional elections.
As to the danger of a runaway convention, we Republicans and conservatives still control a majority of the state legislatures and it would take three quarters of them voting against our principles to change the Constitution against our liking.
In my view we have to balance the risks of driving the country over the cliff if we continue on automatic pilot or facing a rather limited risk of a runaway convention.
