The DNC's predictions are also directed against the former president He will not debate Vice President Kamala Harris again. Trump has said, “It's just too late, the election has already started,” but Democrats point out that he has participated in October debates in the last two election cycles.

Harris told supporters at a rally in Las Vegas on Sunday night that the campaign would be cheering on “Coach Walz” on Tuesday. But even though the debate is the last scheduled face-off in the 2024 cycle, she warned that “their debate should not be the last word.”

As Democrats continue to lean on Walz's background as a high school social studies teacher and football coach, another prediction says, “Go Coach Walz!”

DNC spokesman Abhi Rahman told CBS News on Monday that the predictions were intended to draw Republicans' attention and remind Americans that Trump would not agree to another debate.

“As Vance takes the debate stage to try to make up for Trump's own poor debate performance, these predictions at Trump Tower NYC are a reminder that Trump and Vance are on their own while Trump remains fearful of returning to the debate stage and to be held.” “I must hold Vice President Harris accountable for his failed record and dangerous agenda,” Rahman said in a statement.

David Schwartz, a trial attorney in New York City, told CBS News that it is illegal to project digital signs in New York City for longer than 60 seconds without a permit.

“The Department of Buildings and New York City Code require permits, including for digital signs and animated signs. We have a very extensive sign law that requires you to get a permit to put up a sign, but now, in the age of digital signs, the laws have changed to include permits for digital signs as long as you keep them longer than sustained for 60 seconds,” he said.

“It's not like anyone is going to jail for it, but it is punishable by a fine. And in this political season, it may just be the cost of doing business,” Schwartz added.

Rahman, a spokesman for the DNC, said they are aware of the law and are complying with it because they will take turns going through individual messages that are available for no longer than 60 seconds.
