Does the Clinton Campaign have something up their sleeve?

Sgt Steven Thomas - Perhaps, but there isn't evidence of any such widespread system being in place. Some of the hysteria around it seemed misplaced, like pointing to what was extremely likely to be a mail merge error as evidence of tampering. Another one I thought was unlikely was the vote switching on the screen. If a developer wanted to write a system that would change the vote it would do it under the waterline and the voter would have no visual indication that it happened at all. More likely that is caused by user error combined with a bad user interface design that creates confusion, similar to the Audi 5000 incidents with acceleration in the 1980's.

That's not to say it isn't occurring, there are sporadic credible cases. There just isn't evidence it is occurring in a more coordinated way. My opinion is, of course, subject to change given new information. :)
