The editors of The Dallas Morning News are so repelled by Donald Trump that for the first time in 75 years, they’re endorsing a Democrat for president: We recommend Hillary Clinton for president.

There is only one serious candidate on the presidential ballot in November. We recommend Hillary Clinton.

We don’t come to this decision easily. This newspaper has not recommended a Democrat for the nation’s highest office since before World War II — if you’re counting, that’s more than 75 years and nearly 20 elections. The party’s over-reliance on government and regulation to remedy the country’s ills is at odds with our belief in private-sector ingenuity and innovation.

Trump’s values are hostile to conservatism. He plays on fear — exploiting base instincts of xenophobia, racism and misogyny — to bring out the worst in all of us, rather than the best. His serial shifts on fundamental issues reveal an astounding absence of preparedness. And his improvisational insults and midnight tweets exhibit a dangerous lack of judgment and impulse control.

After nearly four decades in the public spotlight, 25 of them on the national stage, Clinton is a known quantity. For all her warts, she is the candidate more likely to keep our nation safe, to protect American ideals and to work across the aisle to uphold the vital domestic institutions that rely on a competent, experienced president.

This is a stunner — Texas’ main conservative newspaper throwing its support behind Hillary Clinton. Donald Trump’s egomania is so extreme he won’t even blink at this, but his campaign staff has to be getting a sinking feeling.
