1. 6 primaries to watch in Minnesota and Wisconsin
It's been a busy few days for politics in the Midwest. Last Tuesday, Vice President Kamala Harris selected Minnesota Gov. Tim Walz as her running mate on the Democratic ticket, the fourth time in the last 60 years that a Minnesotan will be the Democratic vice presidential nominee. And this week, Minnesota and Wisconsin will hold primaries for federal and state legislative offices, dominating the slate of primaries happening on Aug. 13 (Connecticut and Vermont also have primaries but don't have any major contests).
