WATCH: MSNBC Panelist Calls Trump's Rants "The Ravings of a Lunatic"

All eyes will be on the debate between Vice President Kamala Harris and convicted felon Donald Trump on Tuesday night, with everyone forecasting their very low expectations for Trump's performance.

At the same time, the corporate media seems to have set a very high bar for VP Harris because she's not a white man.

Trump has already been broadcasting his fears regarding the face-to-face with the former prosecutor, claiming the debate is already "rigged" in the Vice President's favor. 

Thanks to his ego, Trump must show up at the debate on Tuesday to maintain an image of strength to his MAGA base. But Trump's public performances have grown increasingly unhinged in the weeks since VP Harris became the Democratic nominee, and losing to her in the debate would be a devastating blow to Trump's already flailing campaign.

Despite claiming his nonsensical rants are a deliberate tactic called "the weave," there's nothing to explain his non-answer to a question he was asked about childcare during a Q&A at the Economic Club of New York.

Add in his other recent odd behavior--his bizarre question-free press conference on Friday, threatening election workers if they "cheat" to make him lose--and it's easy enough to question what'll happen when Trump is forced to answer to Kamala Harris while standing mere feet away from her.

Corporate media might be "sane-washing" Trump, but Americans are going to see the glaring differences between the two candidates at the debate thanks to Trump's "ramblings of an absolute lunatic," says MSNBC's Molly Jong-Fast.
