In a tweet on Sunday, Senator Bernie Sanders of Vermont thanked supporters for coming out in the thousands to mark the launch of his presidential campaign in Brooklyn, New York.

"Thank you to the 13,000 people who came to Brooklyn yesterday to officially launch our campaign," he said.

The independent senator also offered words of gratutute to "the many more who followed along online, and our volunteers who made our rally possible."

"It was an incredible day," he said. "Let's keep the movement going."

While Sanders's official campaign launch attracted a significant audience, with the Vermont senator saying there were at least 13,000 people gathered at the event, the number falls short of the 20,000 people estimated to have shown up at Senator Kamala Harris's campaign launch.

Throughout Harris's 2020 campaign kick off, which took place on January 27 in Oakland California, several commentators took note of the size of the crowd.

Commentators also noted that the estimated crowd size, if accurate, would have also meant that Harris drew an even bigger crowd at her presidential campaign launch than Barack Obama did when he announced his own presideintial run in Illinois in 2017 to an estimated 15,000 people.

Even President Donald Trump, who could soon find himself facing off with Harris or Sanders come 2020, had words of praise for the California senator's ability to draw a large crowd.

In an interview with The New York Times more than a month ago on who among his potential Democratic challengers had had the biggest campaign rollout by that point, Trump said: "The best opening so far would be Kamala Harris."

Pronouncing Harris's first name as "Kameela," the U.S. leader praised the California senator for her "enthusiasm" at her campaign launch and said she had a "better crowd" compared with other Democrats.

"I would say, in terms of the opening act, I would say [it] would be her," Trump said.

While Trump had praise for Harris, he said other presidential campaign launches had fallen "very flat."

"I do think Elizabeth Warren's been hurt very badly with the Pocahontas trap," Trump said, once again using the same slur he has repeatedly hurled at the Massachusetts senator over her claim of Native American heritage.

"I may be wrong, but I think that was a big part of her credibility, and now all of a sudden it's gone," he said.

Other potential contenders, Trump said, had "really drifted far left," though the U.S. leader did not name anyone in particular.

At his campaign launch, Sanders condemned Trump as "the most dangerous president in modern American history."

Sanders also predicted that he would win the Democratic nomination, despite entering a crowded field of contenders now in the double digits.
