He doesn't actually "get away" with it. A lot of people, left and right, are unhappy about tariffs. But for now, he controls the executive, so it is what it is.
The blue wave will likely be a result of blue turnout and some small number of red sitting at home. And sadly the senate is still a toss up
When Obama put a tariff on Chinese tires, right-wingers (correctly) argued that it was a bad idea that caused American consumers to pay almost a million dollars per "job saved" in the tire industry.
Today the right is in control of the executive, the legislative, the judicial, and and far more news media and... basically just crickets.
As for "he controls the executive". Bullshit. When a Democrat is in office, right-wingers remember that the President is not a king.
Please don't "both sides" this extremely one-sided attack on the American worker.
