The Dallas Morning News issued a scathing editorial Tuesday that slammed Donald Trump’s temperament and policies. It marks the first time the newspaper has refused to endorse the Republican nominee for president since 1964, according to The Hill.

In the piece, titled “Donald Trump is no Republican,” the newspaper’s editorial board reasoned that Trump does not champion Republican principles like individual liberty and a strong national defense.

“Trump is — or has been — at odds with nearly every GOP ideal this newspaper holds dear,” it read. “Donald Trump is no Republican and certainly no conservative.”

The editorial board also cited some of Trump’s most infamous statements this election cycle, including his praise for Vladimir Putin and his calling the Trans Pacific Partnership the “rape of our country.” The editorial board recognized that those positions were subject to change, however.

“It’s not easy to offer a shorthand list of such tenets, since Trump flips from one side to the other, issue after issue, sometimes within a single news cycle,” the editorial continued. “Regardless, his ideas are so far from Republicanism that they have spawned a new description: Trumpism.”

While it neither referenced its long history of endorsing Republican nominees nor opted to endorse Hillary Clinton instead, the board made one thing clear: it was not about to support Trump or ask others to do so.

“Trump doesn’t reflect Republican ideals of the past; we are certain he shouldn’t reflect the GOP of the future,” the editorial concluded. “Donald Trump is not qualified to serve as president and does not deserve your vote.”
