WATCH: Morning Joe Digs Into Donald Trump's Latest Conspiracy Theory

On Wednesday's edition of Morning Joe, the panel discussed Donald Trump's latest theory that Joe Biden will attempt to win back the Democratic nomination. 

Donald Trump would really, really like for Joe Biden to be his opponent again. Kamala Harris is surging in the polls and her incredible momentum doesn't seem likely to stop anytime soon. 

A desperate Trump took to Truth Social last night and essentially made up a story where Joe Biden will come to the Democratic National Convention and try to become the candidate. 

After playing a clip of the Harris/Walz rally from last night, Joe Scarborough opined, "What a split screen if you are a suburban voter outside of Milwaukee, outside of Detroit, outside of Philly, outside of Atlanta. If you're in the northern suburbs of Atlanta and you didn't vote for Trump in 2020, but you think you might in 2024, there is your split screen."

The host then continued:

"Look at him [Tim Walz] smiling on stage, look at the screaming crowds — it looks like winners. I will say as a Republican ... I was a former Republican, I'm not used to Democrats looking like winners. They are usually in a crouched position and they are usually scared of their own shadow, with the exception being Barack Obama. Visuals yesterday were striking and compare that with Donald Trump's lonely rants on truth social, that is a striking contrast."
