As it has increasingly since Alec Baldwin first smeared himself in orange makeup to play Donald Trump in 2016, S.N.L. outsourced its biggest impression of the night this weekend to a non-cast member and major celebrity. Matt Damon yelled, cried, and sniffed his way through a coked-out impression of Supreme Court nominee Brett Kavanaugh. It wasn’t exactly searing comedy—the sketch often seemed more like a transcript of Thursday’s Senate Judiciary hearing. But could Damon’s shouting performance have an impact on the audience that matters the most?

When the real hearing aired earlier this week, several pundits noted that both Kavanaugh and Senator Lindsey Graham appeared to be playing directly to an audience of one: President Trump. Kate McKinnon, under prosthetics and sporting a thick Southern accent, underlined that exact point during her Graham impression, saying that the senator’s screaming performance was also an audition for Trump’s Cabinet. Kavanaugh’s defensive and often seemingly false testimony was almost Trumpian. Almost.

One thing Trump doesn’t do when attacked is show any frailty—but Damon’s impression of Kavanaugh underlined just how emotionally volatile the would-be justice was on Thursday. Because Trump will almost certainly see Damon’s appearance, this could end up being very bad for Kavanaugh.

Washington insiders believe that Melissa McCarthy’s popular impression of Sean Spicer was at least partially responsible for the former press secretary losing his position at the White House. “Trump doesn’t like his people to look weak,” a source told Politico of the president’s reaction to McCarthy’s wicked, incisive performance.

Despite publicly supporting Kavanaugh, Trump was reportedly already displeased with his testimony on Thursday. “He’d rather see a man keel over from a heart attack, trying to restrain himself, than bawling in front of the nation,” Trump biographer Michael D’Antonio, author of The Truth About Trump, told People. “He is just not a person who tolerates displays of emotion like this.” Kavanaugh was further made a laughingstock this week when a video splicing his testimony together with footage of Samuel L. Jackson in Pulp Fiction went viral. Now it’s possible that Damon’s S.N.L. performance could further undermine Kavanaugh’s chances—especially if Trump decides he’s no longer a horse worth backing.
