WaPo:

Conservative state legislators frustrated with the gridlock in Washington are increasingly turning to a plan to call a convention to consider a new amendment to the U.S. Constitution — an event that would be unprecedented in American history and one that could, some opponents predict, lead to complete political chaos.

Legislators in 27 states have passed applications for a convention to pass a balanced budget amendment. Proponents of a balanced budget requirement are planning to push for new applications in nine other states where Republicans control both chambers of the legislature.

If those applications pass in seven of the nine targeted states, it would bring the number of applications up to 34, meeting the two-thirds requirement under Article V of the Constitution to force Congress to call a convention.

What happens next is anyone’s guess.
