WATCH: Sarah Palin at the Western Conservative Summit: “At times like this, you cannot be lukewarm”

“They use that never hashtag,” she said of the #NeverTrump movement. “I just call them Republicans against Trump. Or RAT for short!”

In an alliteration-filled speech to a two-thirds full ballroom at the Western Conservative Summit, Sarah Palin ripped into the Republican Party establishment and demanded unity behind nominee Donald Trump.

She heaped praise on Republican Senate candidate Darryl Glenn, who was supposed to introduce her but did not and thanked Colorado for sharing him with the nation. She made a distasteful gesture as she thanked Colorado Republicans for putting up with what they have to put up with “inside the tent” and said she’s glad the tent is getting bigger.

Trump, Palin said, is an unabashed billionaire who respects the working class and will create the conditions for economic prosperity while defeating ISIS, an existential threat to America.

“Armed with secure identities as Americans, people of all persuasions jumped on board the Trump Train,” she said. “Chugging along on the primary trail. Defying the conventional wisdom of the — with all due respect — loser consultants. And I call them loser consultants because they keep losing election after election.”

In language that would be familiar to many supporters of Vermont Sen. Bernie Sanders, she decried “the establishment’s con game.”

“It doesn’t matter to the Beltway Bubble which side wins elections as long as they get to keep their power and their ratings,” she said. “We drove right over that. We drove over those desperate darts flying at our front-runner.”

She did not so much seek to bridge a divide as she demanded loyalty.

Who is threatened by Trump? she asked. “Those GOPers who will never vote for their party’s nominee.”

And the crowd booed.

“They use that never hashtag,” she said of the #NeverTrump movement that is also well represented at the Western Conservative Summit. “I just call them Republicans against Trump. Or RAT for short.”

“This is no time to be lukewarm.  You are either with us or against us.”
