Meghan McCain on Sunday said that Donald Trump’s controversial rally at Madison Square Garden could “backfire” against him.

Trumpspoke in New York at an event many say was planned to mirror an infamous gathering of Nazis in the 1930s. Even some of Trump’s top allies have condemned one “racist comment” from the massive event.

Meghan McCain, the political commentator and daughter of legendary Republican lawmaker John McCain, supports Trump in the election but is worried that the rhetoric at the rally could hurt him nine days from Election Day.

Meghan McCain, who recently made a threat against Democrats that ultimately backfired, took to social media to issue a warning about the event.

“I actually think this rally could backfire. How is this winning over moderates and independents exactly?” she asked. “This is maga on steroids.”

She then added, “It’s a pretty significant and inconvenient demographic you actually need to win – and they don’t freebase maga kool aid every morning.”

Republicans against Trump responded to the comment, saying, “Totally agree.”

Attorney and CNN legal analyst Jeffrey Evan Gold said, “You actually think Americans won’t respond positively to a Nazi rally? It’s always been about the racism.”

“It’s never been about any policy other than racism. Trump’s campaign is over. This the swan song. Done. Fini,” he added.
