The primary races are once again the top story of the week. Mike and Jay start by looking at the state of the Republican race: Trump’s chances in Ohio and Florida, what happened to Rubio, and whether Cruz or Kasich have a real shot at the nomination. They also get into how a contested convention would work, and who might come out of it as the Republican nominee. On the Democratic side, they explain why Bernie Sanders’ win in Michigan – stunning as it was – doesn’t really change the race. After that, it’s a brief foray into the state visit of the highly photogenic Canadian Prime Minister Justin Trudeau, and Jay’s discovery of feminist glaciology.
