The 2016 presidential race was one of the most watched in history.
With just days to go before the Iowa caucuses, Trump had already secured the support of more than 60 percent of registered voters, according to the latest CNN/ORC poll.
But for the third day in a row, the Republican front-runner was out-paced by the Vermont senator in the crowd.
And despite the crowd size, Trump’s supporters weren’t just getting to know the former reality TV star.
The president was also trying to prove that he was the best at mobilizing his base in a way that Sanders and his allies could not.
“I like him, but I don’t think he’s a great campaigner,” Sanders said, after Trump repeatedly criticized his performance in Iowa and New Hampshire.
“You know, he has the temperament, the stamina, the judgment, and the discipline of a professional politician.
That is not something that you can win a primary against.”
Trump responded by reminding his supporters that they had already voted for him in 2016.
“I will be the most effective president of all time,” he said, to roaring applause.
Trump was also quick to blame Sanders for the “craziness” that has been sweeping the country, even as he was able to turn Iowa into a coronation rally.
The campaign did not immediately respond to a request for comment.
Sanders is currently on an 11-day swing through Iowa and South Carolina, as well as a series of rallies across the country in the coming days.
He’s trying to use the two events to expand his delegate lead, while also working to turn out the Republican base in his home state of Vermont.
He’s also planning to continue to make attacks on Clinton.
He said that he plans to bring up her emails and her vote to invade Iraq in the upcoming debate, and to accuse her of using a private email server while secretary of state.
“The Clinton campaign is desperate for negative headlines to push voters to the polls,” Trump said.
“They want to distract voters from her record.
They want to say that she lied to the American people.
They just want to go after her and the American economy.
They’ve been doing it for the last four years.
They’re not going to stop.”
Sanders has been using the rallies to argue that the Democratic establishment is conspiring against him, with the president even saying that the Vermont Senator has “gone soft.”
The president has been doing all of this for the past four years, Sanders said.
While the former president was making his case, Sanders had a rally to himself.
It was the perfect moment to do a rally with Donald Trump, Sanders told the crowd gathered in the basement of a hotel.
When the sun came up on Friday afternoon, Trump was still in his signature red suit and white tie.
Inside the hotel ballroom, the crowd of supporters began to cheer and chant his name.
The crowd was even louder, as Sanders supporters chanted his name with abandon.
But Trump’s campaign manager, Corey Lewandowski, was quick to point out that the crowd was still overwhelmingly Democratic.
“We have a very, very small group of supporters that are against Donald Trump,” Lewandowski said.
