Political giving

Federal giving

Penner is an active political donor with a clear conservative bent. In the 2008 and 2010 federal election cycles, Penner donated a total of $68,800, with an 82%/18% split between Republicans and Democrats. He apparently did not give any federal donations during the 2006 cycle.

Examples of state-level giving

  • Louisiana: In October 2011, Penner and his wife each donated $5,000 to Kira Orange Jones, a candidate for the Louisiana State Board of Elemetary and Secondary Education (BESE).[12] Orange Jones, the Teach for America head in New Orleans who was elected to the BESE in this fall’s election, is said to have “[run] as the embodiment of post-Katrina reform efforts in New Orleans”—reform efforts that have been focused on charter schools and school privatization. Penner is on the board of Teach for America.
  • California: In 2006, Penner contributed $250,000 to “No on 82.”[13] The initiative, sponsored by actor and director Rob Reiner, sought to establish a universal preschool system in California for four-year-olds by placing an additional income tax on individuals making more than $400,000 a year, and couples making in excess of $800,000.[14]
  • Wisconsin: Penner and his Walmart heir family members have furthered their interests in school privatization by funding Republican candidates for state office in Wisconsin, a state none of them lives in. As the Wisconsin Center for Investigative Journalism reported in September 2011, Greg Penner was the fourth-largest individual contributor to winning state legislative candidates in the 2010 elections that put Republicans in control of the state government. Under the first budget passed by Gov. Scott Walker and the Republican-majority legislature, funding for public schools was cut by $800 million over two years, while funding for programs that funnel public money to private schools increased by $17 million over two years.
