Do you think there will be a recount?

I'm currently taking Professor Halderman's class "Introduction to Computer Security" at U of M. On Election Day he gave a lecture on the history of voting system integrity and security, and he gave a few examples of rather simple exploits of voting systems currently in use across the US. I'm not surprised that he's leading the charge in asking for a closer look at these results. However, the claim that "The computer scientists believe they have found evidence that vote totals in the three states could have been manipulated or hacked" seems out of place for him to say and seems more like a misunderstanding by a non-computer scientist source. Halderman and his colleagues probably do not have proof of tampering, but are merely suggesting it is possible and should be looked into.
