MSNBC host Nicolle Wallace, who is facing intense scrutiny after controversial comments she made about a young cancer survivor featured in President Trump’s recent address to Congress, has seen a significant drop in viewership since the Nov. 5 election, according to Nielsen figures.

Wallace, the former communications official for George W. Bush who gained attention for her critical coverage of Trump throughout his presidency, saw her ratings suffer after Democrats lost power.

From the start of 2024 until Election Day, her show averaged 1.6 million viewers, but in the aftermath of Trump’s victory, that number plummeted by 35% — falling to just over one million viewers for the remainder of the year, Nielsen figures show.

The decline was also evident in the key advertising demographic of adults aged 25-54, where she saw a drop from 144,000 viewers before the election to 93,000 after.

Since Jan. 1, the trend has continued, with “Deadline: White House” averaging 1.1 million viewers — marking a 25% decline compared to the same period in 2024.

Competing programs on Fox News, which air in the same 4 p.m. to 6 p.m. time slot, have significantly outpaced Wallace’s viewership, drawing an average audience of 3.6 million. Fox News shares common ownership with The Post.

Even in the key 25-54 demographic, Wallace has lagged behind, with 108,000 viewers — trailing cable offerings like “Diners, Drive-Ins & Dives” on Food Network and BET’s “Tyler Perry’s Sistas.”
