March 8, 2021 at 6:00 a.m. PST Richard Zoglin is the author, most recently, of “Elvis in Vegas: How the King Reinvented the Las Vegas Show.” … The first crisis of the Biden administration could be looming: America may have a president, the first in generations, who is impervious to impressionists. Oh, they’ve tried. SNL cast member Alex Moffat is the show’s latest Biden, but after one appearance, he seems to be missing in action. The late-night comics have barely tried. And where are the YouTube parodies? This cannot be good for the country. … But Biden, so far, has been impregnable. The voice is too bland and devoid of obvious quirks, and beyond the occasional “C’mon, man,” his conversational manner too muted and self-effacing, to give the parodists much to work with. Trump supporters and Fox News pundits would undoubtedly attribute this to the media’s liberal bias. And to be sure, Trump was viewed by the (mostly liberal) satirists not just as an irresistible comic target but also as a dire threat to the nation. Biden’s pleasantly boring presidency has been a welcome return to normality — but hardly great material for parody.
