Trump's rally crowds number is being targeted by Harris.

The Democratic National Committee plans to mock former President Trump on Thursday over his alleged obsession with the size of his rally crowds and those of Vice President Kamala Harris.

The DNC is planning to release a video of Harris mocking Trump about crowd sizes from the first presidential debate on Tuesday.

A mobile billboard will play a video while circling the Tuscon Music Hall, where Trump will hold a campaign event in Arizona on Thursday.

In the video clip from Tuesday's debate, Harris discusses Trump's comments at his rallies, which the Democrats describe as "incoherent ramblings."

In the debate, the vice president pointed out that Trump often discusses fictional characters, such as Hannibal Lecter from "Silence of the Lambs," and claims that windmills cause cancer.

Exhaustion and boredom are causing people to leave Harris' rallies early.

During the debate, Trump politically benefits from the issue of border security, which caused Harris to shift the spotlight to crowd size while answering a question on the topic.

Trump countered Harris' statement, asserting, "She claimed that individuals depart from her events. Individuals do not attend her rallies. There is no justification for attending."

"The former president stated that the people who attend are being bused in and paid to be there, and then shown in a different light. This, he claimed, prevents her from discussing that."

For years, Trump has attracted massive crowds at his rallies, with some events lasting up to four hours from the start of the pre-show to the end of Trump's speech.

Since becoming the Democrats' 2024 presidential candidate, Harris has attracted large crowds at her rallies, similar in size to those of President Biden. However, her speeches are shorter, typically lasting no more than a half an hour.

Before the debate, the Harris campaign released an ad to provoke Trump by using clips from Obama's criticisms of Trump during the Democratic National Convention.

Despite Trump's upcoming visit to Tuscon, DNC spokesperson Cameron Niven maintained that whatever Trump talks about tonight, it won't be about the concerns of Arizonans.

The 2020 election outcome was determined by one of seven key battleground states, Arizona, and it is likely that this state will again play a crucial role in the 2024 White House showdown.

On Thursday, Harris will hold two rallies in a crucial swing state, North Carolina.
