Republican Sen. John Kennedy of Louisiana, now all over the news after a volatile verbal exchange with Chuck Todd on Meet the Press, is a habitual shape-shifter. Pundits disappointed that the Oxford-educated media hound is suddenly parroting pro-Russian idiocy haven’t been paying attention. Kennedy is for Kennedy, no more and no less.

Kennedy and I were fellows in the same class for the 1990-91 Loyola University New Orleans Institute of Politics. At the time, he was the studiously centrist (with the barest tinge toward center-right) special counsel to conservative, then-Democratic Louisiana Gov. Buddy Roemer. (Roemer switched to the Republican Party in March 1991.)

Kennedy had a mild Southern accent but still sounded rather patrician, befitting his record both at Oxford and as former executive editor of the University of Virginia’s Law Review. His folksy, exaggerated Southern-cornpone accent now is an affectation, mere political theater to stand out among the Senate’s bevy of stuffed shirts. It’s about as authentic as a cow in a camel costume.

Kennedy’s transmogrifications don’t end with his faux-folksiness, though. Far more remarkable is how peripatetic his ideology has been. From his centrist roots, Kennedy first moved rightward, to serving as revenue commissioner for conservative Louisiana Gov. Mike Foster. In 2004, he swung hard left, running as a decidedly liberal Democrat in Louisiana’s “jungle primary” for Senate. He endorsed John Kerry for president over George W. Bush, while being endorsed by liberal New Orleans then-congressman William Jefferson and other state liberals, as centrist Democrats such as retiring Sen. John Breaux spurned him.

Then somehow, four years later, he had switched parties to Republican, and his ideology to notably conservative, to challenge incumbent Democratic Sen. Mary Landrieu’s reelection bid. In 2016, he was finally elected to the Senate as only the fourth-most conservative, and definitely not the most Trump-like, Republican in a multicandidate jungle primary.

Now, though, he has turned into Trump’s pet parakeet, repeating whatever outrageous lines the president emits about how Ukraine, not Russia, was the real culprit in systematically interfering in the 2016 elections. (Some Ukrainian officials did publicly criticize Trump during the campaign, but Kennedy wildly overstated their efforts.) Kennedy did this even though he apparently failed to attend intelligence briefings that reported very much to the contrary. He also has taken to adopting Trump-like insults and mildly profane language at public rallies — but of course in his marble-mouthed accent, creating a sort of Foghorn Leghorn-meets-Manhattan effect.

The question then becomes, who is the real John Neely Kennedy? Is he the buttoned-up Oxfordian I knew in 1991, or the liberal of 2004, or the mainline conservative of 2008 and 2016, or the Southern-fried Trumpist of recent months? The real answer may be that Kennedy is none of those things entirely. It may be that the real Kennedy is nothing but a phony.
