I don’t believe that Senile Joe is ahead at all.
I do; but, only because no one has seen him much. He is being kept off stage and the media, as always with Democrats, are protecting him. People remember Biden as Obama's Veep; they have no idea that he is suffering from dementia.
Eventually, they will have to have him out there, for the debates at least. Although, I think that the Dems are trying to cancel the debates.
Can the Dem Party, assisted by the media, keep a candidate for POTUS completely off stage for the entire campaign? I think they are trying.
