The presumptive Republican presidential nominee made his debut in the state at the Western Conservative Summit only to again lament Colorado’s caucus as a "rigged system” that cost him national delegates.

"Colorado is what taught me a lot about politics. I learned a lot,”
Trump told more than 2,000 people at the convention center in downtown
Denver on Friday. "Because polls came out that I was going to win
Colorado … and I was looking forward to it. And then all of a sudden I
didn’t get the delegates. And I said, ‘What happened to the vote?’ ”



The remarks at the start of his rambling 52-minute speech put the focus on the bad blood in Colorado’s Republican Party
toward Trump’s candidacy just as the party wanted to move forward with a
unified vision ahead of the convention at the end of the month.Former Alaska Gov. Sarah Palin didn’t help in her speech moments earlier, in which she eviscerated the "never Trump” crowd plotting to upset the billionaire businessman in Cleveland — an effort led by a handful of Colorado delegates pledged to rival Ted Cruz."I just call them Republicans against Trump, or RAT for short,” she
said to big applause. "At such a time as this,” she continued, "you
cannot be lukewarm. We are taking our country back and you are either
with us or against us.”

Still, Trump predicted a "tremendous victory” in Colorado this
November against Democrat Hillary Clinton, saying the state is "very
important state in terms of winning the election.”

"We do have to win Colorado,” he said. "We do have to win Colorado. I
will be back a lot, don’t worry about it. I will be back a lot.”
