Chicago is the capital city of rigged elections. They invented it and Democrats in the past few years have learned how to scale it nationwide.
From DailyMail.com:
The inmates, some who are accused of murder, argued guards at Cook County Jail were pushing them to vote - despite some being registered in a different jurisdiction.
They claimed the guards were receiving orders from higher up and were 'just doing what I'm told' when confronted over the move.
It comes amid fears of ballot harvesting as insiders claimed the jail was the 'ideal environment' due to no cameras or election observers.
