One of those evil little things waiting to be sprung on us at the right momemt, should we ever allow it to occur. There was a fairly strong push about 8-10 years back to get a constitutional convention (supposedly limited to a single reform, but several different groups were pushing it on different reforms, and a constitutional convention cannot have limits once it is called). A fair number of States were signing on to the idea. Don't remember the details any more; anyone?
