This doesn’t work? “Bad air” doesn’t move collectively. It doesn’t all go from China to the U.S., where we clean it up.

Only 222 of 6,475 cities assessed by IQAir, a company that measures worldwide air quality, passed WHO air quality guidelines in 2021. IQAir revealed “air pollution above WHO standards by 2 to 3 times” in the US.
Walker’s absurd comment on climate change is consistent with other self-created issues he’s faced.
Walker falsely claimed to be a cop. And acknowledging having three unmarried children. His response to the Uvalde, Texas, school shooting. His business issues.
All of these examples show how much Republicans gambled by backing Walker.
As a first-time candidate, Walker may be a wild card and rough around the edges. He was a legendary football player at the University of Georgia. Trump’s early endorsement for Walker didn’t hurt either.

Every day, that gamble seems worse. Walker is having to acclimate to the speed and attention of a major Senate contest this fall.
Voters notice. A Quinnipiac University survey issued at the end of June gave Warnock a 54%-44% lead over Walker, with more Georgia voters seeing the Republican unfavorably than positively.
Walker was a risky pick for Republicans in a seat crucial to regaining the Senate majority. Even the most cynical Republicans didn’t think he’d be this terrible on the campaign road.
