According to the Atlanta Journal-Constitution, this is how he explained his views on climate change to a group of Republican activists: “We don’t control the air. Our good air decided to float over to China’s bad air. So when China gets our good air, their bad air has got to move. So it moves over to our good air space. Then, now, we’ve got we to clean that back up.”…

This is how he promised right-wing podcast host Glenn Beck a quack cure for covid in August 2020: “Do you know, right now, I have something that can bring you into a building that would clean you from covid as you walk through this dry mist?”

And this is what he said on Fox News two days after the Uvalde, Tex., school shooting: “Cain killed Abel and that’s a problem that we have. What we need to do is look into how we can stop those things. You know, you talked about doing a disinformation — what about getting a department that can look at young men that’s looking at women that’s looking at their social media. What about doing that? Looking into things like that and we can stop that that way.”

Even by the standards of today’s Senate, a body of which Ron Johnson (R-Wis.) is a member, this is incoherent, “Looney Tunes” babble — even if Walker rambled his way around to a generally sensible position: increasing funding for mental health treatment.
