In addition, Wisconsin Right To Life previously used the same address for absentee ballot application letters and phone calls that were sent out shortly before the July 12 Democratic primaries, but after the official deadlines for the applications. The group responded to criticism, saying the phone calls were intended to be for the general elections in August.
Calls placed by TPM to Americans For Prosperity Wisconsin, and to Wisconsin Family Action, were not immediately returned.
Late Update: AFP Wisconsin director Matt Seaholm told the Milwaukee Journal Sentinel that the August 11 date in the mailer was a typo, and that the group is not trying to mislead voters.
"This just went out to our members," Seaholm said. "I'm sure the liberals will try to make a mountain out of a molehill in an attempt to distract voters' attention from the issues."
But what of the self-identified Democratic voters who received them?
Seaholm noted that some critics of his group sign up for AFP material so they can keep tabs on the organization, which backs GOP candidates and causes and was co-founded by billionaire activists David and Charles Koch. He said he couldn't be sure if that is what happened here.
"No (mailing) list is perfect," Seaholm said.
