I live near Chicago, so I know that Illinois isn’t a single party state. One of Illinois’ U.S. senators is a Republican, and the majority of U.S. reps., from Illinois, are Republicans. However, Cook Co. & Chicago are mostly Democrats. The last time that Chicago elected a republican mayor was 1927. In 1995, the republican candidate for mayor received 3% of the vote. After that, the mayoral election became nonpartisan.
I hope that Chicago will elect school board members. The elections would be nonpartisan, and a some Republicans would win, partly because the voters won’t know that those candidates are Republicans.
Okay, Single Party City-State then. ;’)
