I caught a news story a couple days ago. (it was from Illinois or Ohio, IIRC)
this guy works for the company that supplies these computer voting machines, was also a major supporter of Bush (to the point where he had face to face meetings).
so the state was going to bring in his machines for the election in November and the guy promises Bush that "he can deliver" the state to him in November.
I wish I had paid more attention to it at the time. in the end the guys employer required him to resign from the Bush campaign due to the conflict of interest. I'm not sure what that would accomplish other than helping with the appearance of conflict, if he had intended to artificially effect the election, this would do nothing to interfere with those plans.
I'd think the guy shouldn't be allowed to have anything to do with the machines.
