Why Did Pollsters Get Michigan And Wisconsin Primaries So Wrong?

Polling for races in Michigan and Wisconsin did not accurately reflect the actual election results due to open primaries and the willingness of further-left candidates' bases to be surveyed, pollsters said.

Surveys indicated that Democratic Michigan Senate nominee Abdul El-Sayed and Democratic Wisconsin gubernatorial candidate Francesca Hong held double-digit leads ahead of their primaries, although El-Sayed narrowly won his race and Hong lost. Pollsters stated it was difficult to properly conduct surveys in these states because of their open primaries, while supporters of further-left candidates are more enthusiastic and willing to participate in polls.
