Illinois election results show gerrymandering's bad outcome
The 2024 national election is behind us. Much of the attention was on the presidential race and seven battle ground states. Then there were some key senate races like Ohio and Montana that drew national attention (and big money) given how they impacted which party would win majority control. Lastly, the battle for control of the House of Representatives came down to a few key house districts in Maine, California, Iowa and Ohio.Never once was Illinois in any such conversations, given how well the Illinois state legislature gerrymandered the state.Among Illinois’ 17 House districts, 14 were won by Democrats and three by Republicans, which the gerrymander guaranteed. Among the 14 Democrat wins, 12 were won by at least 10 points. The closest races were Districts 6 and 17, which the Democrats won by just over eight points each.Among the three Republican wins, two were uncontested and the other was won by nearly 50 points. This illustrates how well Republican voters were packed into these three districts, effectively diluting their influence in the other 14 districts and any chance that the 14-3 outcome would be upset.

Local elections with no competition
It gets even worse when one looks at the Illinois Senate and House.
