Does your entire post refer to constitutional conventions?
If so, note that this is the first and only reply here that does. All the others refer to an Article V Amendments convention.
I'd be fearful of a new Constitutional Convention, as you outline. But, I welcome with open arms an Amendments Convention.
I did take the discussion out of context for which I’m having a bit of an Emily Litella moment. I would support amendments to the existing Constitution that, for example, established reasonable Congressional term limits, established presidential line item veto, and repealed the 16th amendment. But I also have to admit to a certain queasiness about what today’s politicians might do to damage the first and second amendments if they were given a clear shot (pun intended).
