National Democrats are plastering Milwaukee with positive messages today about President Biden while also attacking the 2024 Republican presidential hopefuls just hours before their first primary debate.

The Wisconsin city is playing host to the event, moderated by Fox News’ Bret Baier and Martha McCallum, where eight GOP candidates will take the stage at 9 p.m. ET.

Before they go on, the Democratic National Committee coordinated with Biden’s re-election campaign to roll out several billboards across the city and its highways. 

The DNC is also having an airplane circle the area overhead from 4 p.m. to 8 p.m. CT.

"As 2024 Republican presidential candidates prepare for the first Republican primary debate tonight, the DNC is rolling out a series of billboards and a plane across Milwaukee hammering the most extreme slate of candidates in history," the DNC said on Wednesday morning.

"A plane will fly around Milwaukee on Wednesday with a banner reading: ‘GOP 2024: A Race for the Extreme MAGA Base.’ A mobile billboard will also circle the debate venue on Wednesday, introducing the MAGA field with details about each of the candidates’ extreme and out-of-touch agendas."

DESANTIS, SCOTT, HALEY, PENCE, RAMASWAMY, OTHERS AIM FOR ‘VIRAL BREAKTHROUGH’ AT FIRST DEBATE

The DNC’s billboards will feature a photo of Biden and Vice President Kamala Harris, touting success on a "record number of new jobs," "lowering costs," "updating our nation’s roads and bridges" and "protecting a woman’s right to choose nationwide."

The Biden-Harris 2024 campaign’s billboards throughout the city will feature the "Dark Brandon" meme depicting the president’s eyes shining bright red. Calling Biden "Brandon" began as a joke in Republican circles, but the president’s allies have since seized on it as their own online meme.

DESANTIS VOWS TO PUSH BACK IF HE COMES UNDER ATTACK AT FIRST GOP PRESIDENTIAL DEBATE

The DNC’s mobile billboard will shuffle slides of all eight candidates due on stage Wednesday night with the heading "2024 MAGA Cheat Sheet," and outlines what Democrats say are extreme positions, particularly on abortion.

It comes days after Biden’s campaign announced it would shell out $25 million on a 16-week ad campaign aimed at voters in swing states, the third such substantial purchase by the president’s re-election team.

Republican presidential candidate and political newcomer Vivek Ramaswamy, seemingly following Democratic 2024 contender Robert F. Kennedy, Jr.'s viral pushup trend, shared his own workout video dubbed part of his "debate prep" before taking on fellow GOP White House hopefuls during the first primary debate in Milwaukee Wednesday. 

"More debate prep this morning, with my favorite sparring partner," Ramaswamy wrote on X, formerly Twitter, on Tuesday, sharing a video of him and his wife Apoorva Ramaswamy doing burpees in a garage gym with the song "Bring Em Out," from artist T.I.’s 2004 album "Urban Legend," sounding off. 

A shirtless Ramaswamy, a tech entrepreneur and the youngest presidential candidate at age 38, was seen in another video shared to his X account Monday audibly volleying tennis balls on the court. "Three hours of solid debate prep this morning," he wrote, sharing an American flag.

The videos, respectively viewed millions of times, seem to follow the growing trend set by Democratic presidential candidate Kennedy, as well as billionaire tech rivals Elon Musk and Mark Zuckerberg, publicly boasting about their physical fitness and strength in training footage shared online.

In June, 69-year-old RFK Jr. shared a video on X of himself – also shirtless – banging out nearly 10 pushups. 

"Getting in shape for my debates with President Biden!" he captioned the video, which garnered 17.5 million views as of Wednesday. 

Fitness influencers and conservative activists championed Kennedy for his physical abilities – and muscular, tan physique – after another video of his bench-pressing skills went viral. 

Some praised the videos as an inspiration for men especially, while others juxtaposed the display against 80-year-old Biden's repeated gaffes and public falls and stumbles. 

VIVEK RAMASWAMY CLARIFIES REMARKS AFTER HE IS ACCUSED OF FLOATING 9/11 CONSPIRACY

Ramaswamy, who says that the United States is at a "1776" moment on the cusp of a hopefully new, positive "revolution," is to stand center stage along with Florida Gov. Ron DeSantis during the first GOP primary debate to be hosted by Fox News in Wisconsin at 9 p.m. ET. 

Standing alongside them will be former Vice President Mike Pence and former ambassador and former South Carolina Gov. Nikki Haley.

Former New Jersey Gov. Chris Christie and Sen. Tim Scott of South Carolina will stand in the number five and six positions, while former Arkansas Gov. Asa Hutchinson and North Dakota Gov. Doug Burgum will stand on the wings of the debate stage. 

Former President Donald Trump, the current front-runner for the 2024 GOP nomination, has said he is opting out of the debate. In a TRUTH Social post early Wednesday, Trump said he would "proudly" surrender Thursday on his fourth indictment out of Fulton County, Georgia, related to alleged 2020 election interference.
