"Some senators get so whacky in the national spotlight that they can’t function without it."

"Trump had that effect on Republicans. Before Trump, Lindsey Graham was almost a normal human being. Then Trump directed a huge amp of national attention Graham’s way, transmogrifying the senator into a bizarro creature who’d say anything Trump wanted to keep the attention coming. Not all senators are egomaniacs, of course. Most lie on an ego spectrum ranging from mildly inflated to pathological. Manchin and Sinema are near the extreme. Once they got a taste of the national spotlight, they couldn’t let go. They must have figured that the only way they could keep the spotlight focused on themselves was by threatening to do what they finally did last week: shafting American democracy."

Writes Robert Reich in "Where egos dare: Manchin and Sinema show how Senate spotlight corrupts" (The Guardian). 

Is it "whacky" or "wacky"? The author of "Common Errors in English Usage" says:

Although the original spelling of this word meaning “crazy” was “whacky,” the current dominant spelling is “wacky.” If you use the older form, some readers will think you’ve made a spelling error.

But the OED has the oldest example as "wacky," in 1935, though "whacky" also appears early on, in 1938. "Wacky" looks predominant, but "whacky" is also good. Still, a "whack" is a hard hit, so you might think about whether you want that image infecting the meaning which is just "Crazy, mad; odd, peculiar." 

The OED tips me off that "wackier" appears in John Irving's "World According to Garp." I'm printing it here because to me it's much more interesting than Reich's going on about the mental aberrations of Sinema and Manchin:

There was also a bad but very popular novel that followed [spoiler deleted] by about two months. It took three weeks to write and five weeks to publish. It was called Confessions of an Ellen Jamesian and it did much to drive the Ellen Jamesians even wackier or simply away. The novel was written by a man, of course. His previous novel had been called Confessions of a Porn King, and the one before that had been called Confessions of a Child Slave Trader. And so forth. He was a sly, evil man who became something different about every six months.

I like the phrase "drive [them] even wackier or simply away." There must be a Greek word for that structure, the intentional and surprising lack of parallelism ("wackier" being an adjective and "away" an adverb).
