Tim Walz may be on the national ticket, but he's the ultimate downballot guy, so we've got to talk all about him on this week's episode of "The Downballot." We recount Walz's extensive electoral career, starting with his upset win for Congress as a "Fighting Dem" during the 2006 wave that began a streak of impressive overperformances continuing through his two bids for governor. We also explain exactly how Walz would be replaced if he's elected VP—and how his replacement would be replaced, and how that person would be replaced. Nothing is too weedy for us!Co-hosts David Nir and David Beard also recap Tuesday's meaty primary night, which set the table for a host of competitive November elections and set some other candidates on a glide path to victory. The Davids discuss why the top of the ticket will likely determine the fate of Michigan's open Senate race; why candidate quality—and not outside money—was the most important factor in Rep. Cori Bush's defeat; and why Washington's top-two primary system should be banished from the face of the earth.
