Ballotpedia:Who Runs the States, Illinois
The two major political parties claim that their policies will lead to better outcomes. What does the data show?
At Ballotpedia, we explored these issues in a three-part study, Who Runs the States.
This page takes a specific look at how Illinois performed in the study.
Background about the study
- See also: Ballotpedia: Who Runs the States
Part One examines the partisanship of state government from 1992-2013. Part Two establishes a State Quality of Life Index (SQLI), aggregating a variety of existing state indices into one measurement. Part Three will overlay the two reports, looking for trends and correlations.
State government analysis
From 1992 to 2013, there were Democratic governors in office for the first 11 years while there were Republican governors in office for the last 11 years. During the final 11 years of the study, Illinois was under Democratic trifectas.
Across the country, there were 493 years of Democratic governors (44.82%) and 586 years of Republican governors (53.27%) from 1992-2013.
Over the course of the 22-year study, state governments became increasingly more partisan. At the outset of the study period (1992), 18 of the 49 states with partisan legislatures had single-party trifectas and 31 states had divided governments. In 2013, only 13 states have divided governments, while single-party trifectas held sway in 36 states, the most in the 22 years studied.
From 1992 to 2013, the Democratic Party was the majority in the Illinois State Senate for 12 years while the Republicans were the majority for 10 years.
Across the country, there were 541 Democratic and 517 Republican state senates from 1992 to 2013.
Illinois House of Representatives
From 1992 to 2013, the Democratic Party was the majority in the Illinois State House of Representatives for 20 years while the Republicans were the majority for 2 years. The Illinois State House of Representatives is one of 18 state Houses that was Democratic for more than 80 percent of the years between 1992 and 2013.
Across the country, there were 579 Democratic and 482 Republican State Houses of Representatives from 1992 to 2013.
Partisan control changes
There were four partisan control changes in Illinois during the study period, the same as the average number of changes in the 50 states.
