We present data from the 2016 presidential election recounts done in Wisconsin and Michigan and information about the voting technologies that were used there to explain why it is challenging to show that the voting technologies treated candidates Trump and Clinton symmetrically. Lack of clarity about which type of technology was used to record vote counts, a mix of mostly small but sparse large counted differences between original and recounted vote totals, features that relate to voters, technologies and recount methods, and selectivity concerns are among the obstacles.
