Even at its wildest moments, the musical “Ghost of John McCain” finds its humor neutralized by the specter of Donald Trump, and the divisive politics that swirl around him.

Even so, the cast sometimes rises above the material. Lindsay Nicole Chambers makes a sly Clinton and a hilarious composite Trumpian “daughter-wife.” Jason Tam is a beamish yet dignified McCain, except when competing in a debate with Trump that is staged, by the director Catie Davis, as a chaotic dance-off.

The play sees the late McCain living in Trump's head as the latter wants to hear he was the best president in history.

The off-Broadway musical “The Ghost of John McCain” is an oddball tribute to the late senator – though Meghan McCain said it’s “trash.”

The musical begins with the 2018 death of McCain, who arrives onstage spiffily dressed in a white suit, lugging a wheeled tote and, as played engagingly by Jason Tam, looking not a day older than when he was released from the Hanoi Hilton. In the jaunty musical number “Heaven or a Three-Star Hotel,” McCain wonders where, exactly, he’s landed.

Ghost of John McCain officially opens off-Broadway tonight at SoHo Playhouse. All new photos and a video sizzle reel have been released, showcasing some of the show’s characters including ‘Donald Trump’s Brain,
