Maybe, but once convened, a new constitutional convention could result in the repeal of our existing one. Just adhere to the one we have, for goodness sake.
Might be some merit to your argument.
On the other hand, the reason we are in the current position is because we have been too timid to take any sort of positive action. We are so good with the "what ifs" that we prefer the status quo (which is a continuing decline in our Freedoms due to Left-Wing activism, abetted by entrenched Dems) and it insures our eventual demise.
