We had a presidential primary in Washington State this week, and if you're confused as to why this happened at the end of May, when Donald Trump is already the Republican nominee and Washington State already had its Democratic caucuses two months ago—well, you are not alone.

So I hauled in the sitting Washington Secretary of State, Republican Kim Wyman, to explain—at 1:59—why we just spent over $11 million in public money on a bunch of voting that doesn’t really change anything.

I also tracked down Tina Podlodowski, the Democrat who’s running to replace Wyman this year, and at 10:47 we hear her view.

After that, at 22:14, a University of Washington grad student who knows what a warmer earth might look like because it’s happened before, millions of years ago.

And finally, at 29:28, the general manager of Seattle’s KPLU radio gives an update on the campaign to save KPLU from being bought up by its competitor, KUOW. Plus, as always, the music of Ahamefule J. Oluo.
