There’s no need to completely throw out the Constitution and write a new one that starts a new republic. Doing so might throw out many of the important constitutional rights and protections that have been established over the years, not only directly but also through court decisions. It would be essentially starting from scratch, and only if done very carefully might it be better. I think a Constitutional Convention significantly revising the current Constitution but keeping it fundamentally intact and preserving continuation of the republic that began in 1789 would be best.
I’m curious, which rights do you think would be in danger?
