Call for a Constitutional Convention to propose a Balanced Budget amendment?

[zorkpolitics]

Apparently John Kasich is leading an effort to have the states call for a Constitutional Convention to propose a Balanced Budget amendment:

Apparently 23 states (of the 34 needed) have passed resolutions calling for the convention.  Besides OH and MI, does anyone know what other states have called for a Balanced Budget Constitutional Convention?

Previous drafts of such a Balanced Budget amendment attempt to be somewhat realistic, they would allow deficit spending in time of "National Emergencies", presumably war or severe recessions. 
If the feds ran a Clinton era surplus of about $100 billion/yr it would only take 180 yrs to pay off the national debt.
