Thanks to DUer bleever for the machine error data in response to my post on exit poll deviations and voting machines earlier today.
Machine problems appear to be most prevalent in states with large minority populations - AND A SIGNIFICANT RED SHIFT TO BUSH.
Look at LA! and NM, GA, FL, OH, PA, NY, DC....
Punched cards and Levers: NY, OH, PA, CT (Red Shifts beyond the MOE) and LA.
Touchscreens and Optiscans: FL, GA

It's the Red Shift again, this time the deviations weighted by Electoral Vote. This graph shows where Bush got his biggest popular vote bang for the exit poll deviation buck.

Also included on the graph for each state: the voting machines used, by percentage. Thanks to Pobeka for this data.
The punched cards and Lever machine states are interesting.
Check NY. Punched cards using Levers. Could it be that lots of the punch cards were spoiled due to machine malfunction or something else? Could it be that this has been going on forever as these machines go way back to the beginning of the 20th century?
They say that 3-5 million punched card votes are spoiled every year, due to a combination of machine malfunction and fraud. We know what happened in FL 2000 and OH 2004. Hundreds of thousands of spoiled votes. And the vast majority of them were in Democratic districts.
For those who prefer their data in table form, see Post # 1.
