Is Americans for Prosperity endorsing Sean Duffy for Congress?

It’s common knowledge that non-profit organizations can’t endorse political candidates, to everyone except Americans for Prosperity’s executive director Mark Block, that is.

Block, who in 2000 was fined $15,000 and banned from volunteering or working on political campaigns for 4 years, has raised new questions about activities being conducted by his organization. According to the Wausau Daily Herald:

There’s some question, though, about the event’s treatment of political candidates. The group originally invited U.S. Rep. Dave Obey, D-Wausau, and Republican challenger Ashland County District Attorney Sean Duffy to be guest speakers. Former Obey challenger Dan Mielke, who is vying against Duffy, was not invited.

Block denied that the exclusion was an endorsement of Duffy, but could not offer an explanation. He said the “format” of the event was going to change after Obey declined to attend.

Mielke said he suspects the event is an effort to marginalize him in the election. Duffy said he has no ties to the group but wanted to “take any opportunity” to discuss health care before finding out Friday AFP was rescinding the invitation to speak.
