Supremes OK Gerrymandering: Nichols; Trump & Iran: Jeet Heer; Florida Voting: Abramsky

The Supremes gave the green light to gerrymandering--a disaster, but blocked the census citizenship question; and, the first round of 2020 Democratic nominees debated last night -- John Nichols reports. Next up, Trump and war with Iran: not this week: comment from Jeet Heer, the newly-appointed national-affairs correspondent at The Nation. Plus: The re-enfranchisement of felons who have served their sentences in Florida is law now and the Republicans are attacking it (again) -- Sasha Abramsky reports.
