Clinton received 42 percent and Trump registered 39 percent in the head-to-head poll of likely Colorado voters conducted last week. The close nature of the race is not unexpected, as President Barack Obama won Colorado by roughly 5 percentage points in 2012.

At numerous points in his 45-minute speech, Trump urged his supporters in the campus arena — numbering at more than 3,000, according to local officials — to “get those ballots in.”

The early numbers showing Democrats with the advantage may not foretell the final result Nov. 8, as evidenced by Trump fans at the event.

Thomas Crawford, a registered Democrat from Denver, traveled to Greeley for the rally. He and wife Martha, a lifelong Democratic voter, cast ballots for Trump.

“I think the Clintons have sold this country down the river,” said Crawford, a 49-year-old salesman.

“Trump’s not a politician,” added Martha Crawford, 63. “He’s going to drain the swamp.”
