It's Wednesday, March 20, 2018, from Slate, it's the Gisdai Mike Pesca. Trump dominates the ether. He crowds out other news.

The effect is that other news happens, that is how the world works, even if Trump wishes it weren't so.

But when the news hole is so dedicated to the investigation of the president, presidential initiatives, such as they are, given his drug policy speech, and also West Wing staffing, when all that's getting so much coverage, then we can cover a driverless car crash or a series of bombings in Austin.

But we can't really dedicate a second or third day to tariff exemptions, or, and here's a good point of comparison, or a bridge collapse.

We could cover it for a couple days, but it ends there.

Now in 2007, a bridge collapsed, a bridge collapsed in Minnesota, it killed 12, and I went back. It stayed in the headlines and on the front page of the papers for days and days and days, well over a week.

In 2018, a bridge collapsed. Now this is the pedestrian bridge in Miami near Florida International University, and it killed six.

On the show today, a spiel, a celebration of people who are their own worst spokesman. But first, speaking of cracks in the foundation, Harvard professor and Obama administration official Cass Sunstein has edited a book where his asked top thinkers can it happen here.

And you know what the it is, it's encroaching Trumpism. The answers though are less apparent.

If you're like me, you've learned a lot about indoor air quality over the last couple years. The list of invisible airborne troublemakers. It's a long list. In addition to viruses, we're talking about microscopic allergens like mold spores, dust, pollen.

They just make you all feel miserable. Also, the ultra fine particles, which ain't fine. We're talking about things from wild, fire smoke to gas stoves to car exhaust, which are all linked to lung and heart disease and maybe even dementia.

So an air purifier can make a really big difference. But there are lots of big differences when it comes to air purifier performance. Let me tell you about Brio.
