For instance, Roseville resident Ursela Cowan’s ballot wasn’t counted because she failed to sign the envelope, as required by state law. But in her affidavit Cowan explains that the portion of the envelope that was supposed to contain her signature was obscured by a sticker. “I now understand that I was required to sign the envelope to certify that I was in fact eligible to vote by absentee ballot,” Cowan’s affidavit reads. “However, the certification was almost completely covered by the sticker. Had I been able to read the certification, I would have signed.”

The lawsuit, filed by Minneapolis attorney Charles Nauen, is being financed by the Franken campaign. The plaintiffs reside in 18 counties across the state.
