ThinkProgress has the scoop:

Mitt Romney’s campaign has been training poll watchers in Wisconsin with highly misleading — and sometimes downright false — information about voters’ rights...One blatant falsehood occurs on page 5 of the training packet, which informed poll watchers that any “person [who] has been convicted of treason, a felony, or bribery” isn’t eligible to vote. This is not true. Once a Wisconsin voter who has been convicted of a felony completes his or her sentence, that person is once again eligible to vote.

The training also encouraged volunteers to deceive election workers and the public about who they were associated with. On page 3 of the packet, Romney poll workers were instructed to hide their affiliation with the campaign and told to sign in at the polls as a “concerned citizen” instead. As Kristina Sesek, Romney’s legal counsel who just graduated from Marquette Law School last year, explained, “We’re going to have you sign in this election cycle as a ‘concerned citizen.’ We’re just trying to alleviate some of the animosity of being a Republican observer up front.”

The training also doesn't mention several valid proofs of residency including, shockingly, food stamp correspondences. This is really despicable stuff.
