There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague.  - The President of the United States (POTUS) is the elected head of state and head of government of the United States.

Pledged delegates from all fifty U.S. states and from American dependencies and territories such as Puerto Rico and the Virgin Islands, and superdelegates which are unpledged delegates representing the Democratic establishment, attend the convention and cast their votes to choose the Party's presidential candidate. Like the Republican National Convention, the Democratic National Convention marks the formal end of the primary election period and the start of the general election season.  - Illinois is a state in the midwestern region of the United States, achieving statehood in 1818.

The Port of Chicago connects the state to other global ports from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean, as well as the Great Lakes to the Mississippi River, via the Illinois River.

Illinois has long had a reputation as a bellwether both in social and cultural terms and politics.  - In American politics, a "superdelegate" is an unpledged delegate to the Democratic National Convention who is seated automatically and chooses for themselves for whom they vote. These Democratic Party superdelegates (who make up just under 15% of all convention delegates) include elected officials and party activists and officials. Democratic superdelegates are free to support any candidate for the presidential nomination. This contrasts with convention "pledged" delegates who are selected based on the party primaries and caucuses in each U.S. state, in which voters choose among candidates for the party's presidential nomination. Moreover, superdelegates are permitted to participate in the primary elections as regular voters.
