I know for a fact, Unions in Chicago get favored status with the City of Chicago.
My dad told us stories about how they would sit outside the polling places and watch members vote in elections. The booths would be put up against the windows, the curtains would only go down to about your waist. If a union member walked in and didn't go directly to the left side of the booth, they were about 4-5 feet wide, and pull the straight democratic ticket, it would take less than 5 seconds, they were fired the next day.
Yea, voter fraud what does it get you? How about the folks in Indiana, what did it get them?
What about the list of people from King County in 1960 that were dead and voted in alphabetical order? Take King County and Cook County away and Nixon wins in 1960, yea nothing to gain.
I walk into my registration place with a piece of postcard hand it to the lady and she gives me a code. I can take another postcard that I receive at my other house and go vote again if I wanted too in another location.
If you don't think there is reason too or that voter fraud happens in this country...well I am sorry you can't see something so right in front of your face.
