How do we go about making Southern Illinois a State?

Under Article IV, Section Three of the United States Constitution, which outlines the relationship among the states, Congress has the power to admit new states to the union. The states are required to give "full faith and credit" to the acts of each other's legislatures and courts, which is generally held to include the recognition of legal contracts, marriages, and criminal judgments. The states are guaranteed military and civil defense by the federal government, which is also obligated by Article IV, Section Four, to "guarantee to every state in this union a republican form of government."

New states are admitted into the Union by the precedents and procedures established by the Northwest Ordinance. Following the precedent established by the Enabling Act of 1802, an Enabling Act must be passed by Congress as a prerequisite to admission. The act authorizes the people of a territory to frame a constitution, and lays down the requirements that must be met prior to consideration for statehood.

The logistics of bringing about Southern Illinois Statehood are fairly simple.
First, a petition to request a State wide referendum to consider the question;
Second, a request to Congress to pass an Enabling Act;
Next, a constitutional convention and the drafting of a constitution for the new State;
And finally, fulfill other requirements as directed by Congress.
