Former Republican vice presidential nominee Sarah Palin told the Western Conservative Summit Friday that you're either voting for presumptive GOP nominee Donald Trump or you're a "R.A.T."

It's her acronym for "Republicans Against Trump," which is what she prefers to "Never Trump."

"If you're not with us, you're against us," Palin declared with speaking at the largest gathering of conservatives this year outside Washington, D.C.before the upcoming GOP convention in Cleveland.

"I love the challenge of of not just singing to the choir," Palin added. "I love seeing the exploding heads keep exploding over this movement. Because it seems so obvious… Trump wins, America will win. Voters are so sick and tired of being betrayed."

The Trump surrogate went on to explain that Trump speaks for the "silenced majority" and is "on the side of Joe Six Packs," so he will speak for "all Americans" if elected. She also went on to bash both President Obama and Hillary Clinton for expanding the role of government.

Trump is scheduled to speak at the Western Conservative Summit Friday.
