Besides. The very good points DUMBGRUNT makes is the voter fraud and machine politics that Chicago is famous for.
I very much doubt that Chicago is generating nearly as many legit Democrat votes that are reported each election.
Like California, Illinois has com under the control of Democrats by illicit means.
The only way that they will ever have a clean election again is for there to be an extensive audit of their elections and then have intensive monitoring of elections for decades to come.
Illinois county totals, note the small detail lower right, SIZE OF VICTORY.
There are a few precincts in Chicago that had ZERO Republican votes.
Not likely considering the few that would mistakenly pull the wrong lever.
