I'm very familiar with both Counties. Cook is a hotbed of leftists. DuPage is a hotbed of big government rino swamp dwellers.
The Dupage County courthouse complex is a temple to big government, and headquarters of a very corrupt county government.
Dupage is almost as bad as Cook, if you can't see that you're deluding yourself.
I’ve lived in Dupage County for almost 30 years, and it is nowhere near to being as bad as Cook County; it’s not even close.
