Politicians are neither gods nor saints. Because they aren’t gods, they often make bad policy decisions. Because they aren’t saints, they often try to evade responsibility for their failures, asserting either that they did as well as anyone could have or that someone else deserves the blame.

For a while, then, the politics surrounding the power outages that have spread across Texas looked fairly normal. True, the state’s leaders pursued reckless policies that set the stage for catastrophe, then tried to evade responsibility. But while their behavior was reprehensible, it was reprehensible in ways we’ve seen many times over the years.

However, that changed around a day after the severity of the disaster became apparent. Republican politicians and right-wing media, not content with run-of-the-mill blame-shifting, have coalesced around a malicious falsehood instead — the claim that wind and solar power caused the collapse of the Texas power grid, and that radical environmentalists are somehow responsible for the fact that millions of people are freezing in the dark, even though conservative Republicans have run the state for a generation.
