Randy Bryce needs to convince voters to go from 20 years of representation by House Speaker Paul Ryan to a congressman who wants “Medicare for All,” tuition-free public college, and the abolition of ICE. It’s no small task, but Bill de Blasio is there to lend a hand.

The New York City mayor is set to campaign on behalf of the “Iron Stache” in southern Wisconsin this week. Bryce won his primary easily on Aug. 14 and is now running against attorney Bryan Steil for Ryan’s seat in the House. The district might be more competitive than Ryan’s two decades of comfortable victories suggests, but it’s probably still a little too red for de Blasio to be of much help with voters. Trump won Wisconsin’s 1st District by 10 points in 2016; Ryan won it by 35.
