Have not thought about CoS in a while what with all that has been going on since the 2016 election.
My first thought is the CoS is now much more likely to occur as the progs have made it clear they believe themselves to be above all laws.
I have not seen the proposed amendments lately, I will give them a read.
.
Congressman Ken buck, CO, in his book,”Drain the Swamp” specifically writes that the CoS is the only way to return power to the states. Great read!
