Sarah Palin appeared at today's Teaparty rally in Wisconsin and as can be seen in the screengrab below, she's standing in front of a banner promoting "Americans for Prosperity" and standing at a podium proclaiming "I Am AFP!"
AFP is funded by the billionaire Koch Brothers, owners of Koch Industries. Most on the left oppose them because of their funding of (supposed) conservative causes, including professional global warming deniers and advocates against social welfare programs.
