About

The mission of The State Constitutional Convention Clearinghouse is to educate the public about upcoming periodic referendums on whether to call a state constitutional convention.

Various factors have contributed to the creation of an information vacuum on the subject of periodic state constitutional conventions. These factors include an absence of education on the subject in high school, college, and graduate level courses on American government; lack of academic interest in the subject in the fields of political science, political history, and election law; the infrequent, local, and seemingly quixotic nature of state constitutional convention based democratic reform; and the well-resourced and fierce opposition to state constitutional conventions by state legislatures and groups most effective at exerting influence via state legislatures. Despite these factors, the periodic state constitutional convention serves an essential democratic function within the system of American government. It is also an institution worthy of improvement.

Detailed information about each state with a periodic constitutional convention referendum is not located on this website, but on state-specific subdomains. States with such websites include Alaska, Hawaii, Iowa,  Maryland, Michigan, Missouri, New Hampshire, New York, and Rhode Island.  States that will be added in the next few years include Connecticut, Illinois, Montana, and Ohio.

I am not an advocate for frequent changes in laws and constitutions. But laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths discovered and manners and opinions change, with the change of circumstances, institutions must advance also to keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy as civilized society to remain ever under the regimen of their barbarous ancestors.

Thomas Jefferson, U.S. president and author of the Declaration of Indendence

(inscribed on the wall of the Jefferson Memorial in Washington, DC adjacent to Jefferson's statue)

I know no safe depository of the ultimate powers of the society, but the people themselves: and if we think them not enlightened enough to exercise their control with a wholesome discretion, the remedy is, not to take it from them, but to inform their discretion by education. This is the true corrective of abuses of constitutional power.

Thomas Jefferson, U.S. president and author of the Declaration of Indendence

(Letter to William Charles Jarvis, Sept. 28, 1820)

The Jefferson Memorial

[T]o me the convention mode seems preferable, in that it allows amendments to originate with the people themselves, instead of only permitting them to take or reject propositions originated by others, not especially chosen for the purpose, and which might not be precisely such as they would wish to either accept or refuse.

Abraham Lincoln, U.S. president

(First inaugural address, March 4, 1861)
