"Even though we're doing pretty good in the polls, I don't believe the polls anymore," the GOP presidential nominee told a rally crowd in Colorado Springs, Colo., Tuesday. 
"I don't believe them," he repeated.
Trump accused the media of hiding good polls about him and playing up bad news. It's comments like these that frustrate many Republicans in Washington, who privately kvetch that Trump and his allies are denying reality.
"If there's 10 [polls], and if there's one or two bad ones, that's the only one they show," Trump said. "Believe me, folks, we're doing great. If we keep our spirit, and if we go out and win."
Trump echoed the views of his campaign CEO, Steve Bannon, by claiming he's going to produce a shock result like "Brexit" in Europe, where pollsters were stunned when a majority of British voters decided to leave the European Union. 
"This is another Brexit, believe me," Trump said Tuesday.
Referring to the media, he added, "They are so worried. That's why they've become vicious and hostile and dirty. Because they see what's going on."
Trump appeared to be arguing that his rally crowds provide evidence that he's doing better than the scientific polls indicate.
"This rally," he said, "set up just a short while ago, look at the number of people packed."
At Clinton's rallies, Trump added, "very few people show up when she has the energy to go to the event, which isn't often."
