If that’s your opinion (and I’m not saying you’re wrong), what’s the harm of an Article V convention? You’re basically saying Obama’s going to do whatever he wants regardless of anything we do. Why would calling an Article V convention be harmful? At the very worst, he’d ignore any new amendments stemming from it.
If he’s really going to effectively repeal the first, second, fifth, and any other amendments that he doesn’t like, won’t he just do it? Why would calling an Article V convention change that fact one way or another?
