I wonder how that number would change if everyone that wanted to leave, could. I think it would at the very least be cut in half (every 2.3 minutes) and most likely even more.
I think the number would be huge. I grew up and lived in Illinois for most of my life but fled 11 years ago. Everyone I knew there that could leave has left. Those that stayed did so because of work or they have kids in school.
Illinois was a great place once, but between the illegal wetbacks, high taxes,high crime, and the legendary Firearms Owners Identification Card (FOID Gun Card), there's just no reason to be there anymore.
