Anyone following their ears and eyes --- even if they watch only the Communist News Network -- cannot fail to see that the top of the Dem ticket is senile. Dementia. Cognitive decline. Therefore, if you vote for him, you have to not care about the Dementia Candidate and instead want to install the Demonic Party, including its VP candidate, under-experienced, radical ratialist, and frequently unhinged Kamala Harris. IOW, you have to be convinced of the superiority of Demented and Demonic ideology over pragmatic realities and what your ears and eyes tell you.
Or, you have to believe that it is less risky to usher in the Demonic Party than to re-elect Trump, which means that you have bought into all of the hatred of him systematically pumped into your bloodstream by the the Live Screamed News. (You have to be basing your choice on hatred which others have manufactured and distributed.)
The big question is whether both paragraphs together can produce enough electoral votes to defeat the incumbent. Probably not, but sprinkled with fraud (massive ballot strategies and tactics) and assisted by expensive lawyers, maybe the opposition can pull it off. I think that's what they're banking on.
