LOL, Lake Forest voters probably feel like Orange County folks slowly watching diversity slowly make their state/county bluer.
I have several college friends from Lake Forest ... they are not happy about Illinois' standing as a blue state, and their parents almost can't believe the change in the state's politics compared to the '70s and '80s. Orange County is an apt comparison, haha.
IL was never conservative. But it was GOP. However the GOP was deeply corrupt and they were the ones who actually introduced the income tax in 1969 and put public employee pensions in the state constitution also in 1969
