Don’t mess with the Constitution.
We don’t want to open that can of worms with the current electorate and current representatives/senators/POTUS.
Just fire those representatives/senators/POTUS who refuse to do the people’s will.
Vote them out.
Educate everyone within your sphere of influence.
Individual amendments do not require a full Constitutional Convention. I would never think of opening that Pandora’s Box and argued against that just last April in The Wall Street Journal: http://online.wsj.com/article/SB124105694445071685.html
