To some in the conservative wing of the Republican Party, Donald Trump officially accepting the party’s presidential nomination on Thursday was even more apocalyptic than the tone of his speech, with many mourning the loss of their Grand Old Party.

Here are just a few reactions from conservatives preaching doom-and-gloom about Trump’s ascendance to party standard-bearer.

Conservative talk radio host Meghan McCain declared the party “dead.”

Nicolle Wallace, a conservative commentator who worked in the George W. Bush administration, said during NBC News‘ convention coverage that the party she had spent two decades working for “died in this room tonight.”

Jim Treacher, a Daily Caller writer, also rushed to declare the party’s demise:

“YES YOU WILL, YES YOU WILL, YES YOU WILL!!!” The Republican Party is dead. https://t.co/dvkjcQY6cR — Jim Treacher (@jtLOL) July 22, 2016

Another veteran GOP insider and friend of former Florida Gov. Jeb Bush, Ana Navarro, locked horns with a resident Trump surrogate on CNN, calling Trump’s address “not Republicanism.”

National Review columnist Kevin D. Williamson also made his distress clear on Twitter.

Ben Howe, a conservative strategist who has said he’d vote for Hillary Clinton rather than back Trump, drew a comparison between the real estate mogul and Adolf Hitler and Hugo Chavez:

People who get the vapors every time Hitler is brought up. You understand that at first Hitler wasn’t Hitler right? — Ben Howe (@BenHowe) July 22, 2016

Someone in a better position than I to know points out that Hugo Chavez is a much better comparison. I agree. — Ben Howe (@BenHowe) July 22, 2016

Over at his blog, The Resurgent, RedState.com founder Erick Erickson wrote that “Cheeto Jesus” effectively killed the “spirit of entrepreneurship” and American exceptionalism in his speech accepting the GOP nomination.

“I’m sure in the original German the speech had some nuances that were commendable,” he wrote. “The Republican Party is officially now the party of Trump. Instead of happy warriors, they are angry, bitter bigots…That anger is not going to attract anyone, so they will bully and browbeat.”
