Former President Barack Obama warned about the close race between Vice President Harris and former President Trump in November, while bashing his successor as dangerous, chaotic and unsympathetic.

“This will still be a tight race in a closely divided country. A country where too many Americans are still struggling, where a lot of Americans don’t believe government can help and as we gather here tonight, the people who will decide this election are asking a very simple question, who will fight for me?” Obama said. “Who’s thinking abut my future? About my children’s future?

“One thing is for certain, Donald Trump is not losing sleep over that question,” Obama said, name-checking his successor.

Obama argued that Trump “hasn’t stopped whining about his problems” and is “afraid of losing to Kamala,” adding that he spreads conspiracy theories and has a “weird obsession with crowd sizes.”

“The other day, I heard someone compare Trump to the neighbor who keeps running his leaf blower outside your window every minute of every day,” he said. “Now, from a neighbor, that’s exhausting. From a president, that’s just dangerous.”

“We do not need four more years of bluster and bumbling and chaos. We have seen that movie before and we all know that the sequel is usually worse,” the former president added.

Obama, who was met with a rock star welcome in his home state of Illinois, hailed Harris as a prosecutor, attorney general and vice president. Obama and Harris have a long-standing relationship that stems from her time as attorney general while he was president.

Giving a nod to Gov. Tim Walz (D-Minn.), Obama said Walz is an “outstanding partner” to Harris who “knows who he is and knows what’s important. He joked that the shirts Walz wears don’t come from a political consult but from his own closet and “they have been through some stuff.”

The former president touted Harris’s “bold new plan,” which she released last week, that aims to build new housing units and help first time homebuyers. He also noted that Harris wants to expand the Affordable Care Act, known as Obamacare, by limiting out-of-pocket costs for Americans.

“We need a president who actually cares about the millions of people all across this country who wake up every day to do the essential, often thankless work to care for our sick and clean our streets and deliver our packages and stand up for their rights to bargain for better wages and working conditions,” he said.

“And Kamala can be that president. Yes, she can,” he said, calling back to his popular campaign catchphrase.

Chants of “yes she can” erupted in the crowd.

The speech on Tuesday was Obama’s first public appearance since he was privately behind some of the pressure on Biden to drop out of the race last month and pass the torch to Harris. Within a week of her candidacy, both Obamas endorsed the vice president.
