WATCH: Why George W. Bush Won't Endorse Kamala Harris

While hundreds of Republicans have already endorsed Vice President Kamala Harris ahead of Election Day on Tuesday, there's one name that's been glaringly absent from the lengthy list of GOP member backing Harris/Walz that grows by the day:

George W. Bush.

Bush's former Vice President, Dick Cheney, has already shared his endorsement for VP Harris, as have his wife, Lynn, and daughter, Liz Cheney. GWB's daughter Barbara Pierce Bush recently endorsed the Vice President. And despite calls for GWB to speak up, including from Liz Cheney, he has remained staunchly silent on the 2024 election.

MSNBC's Nicolle Wallace, who was an aide to GWB, made a last-minute plea to her former boss to have a "change of heart" at the 11th hour and endorse Vice President Harris.

"An adviser said he's not going to insert himself into this political moment," Wallace told her viewers, "but in light of the violent nature of the threat toward his former vice president's daughter during the time she served him, and as a dad whose own daughter just last week bravely entered the political fray, campaigning for Kamala Harris, I thought today it was important to share some of George W. Bush's past statements about what America does and what Americans do when they face threats."

However, the pleas will go unanswered for one glaring reason: George W. Bush has close ties to GOP Svengali billionaire Harlan Crow, who has essentially controlled Supreme Court Justice Clarence Thomas for decades. Crow, who collects Nazi memorabilia, sits on the board of the George W. Bush Library in Texas.

Sadly, Wallace's appeal will fall on deaf ears.
