Trump has referred to Biden as Obama by mistake on several occasions in his ridiculous speeches
He's just as senile
Read this pile of drivel he came our with recently at one of his cult rallies....
"Gettysburg, wow--I go to Gettysburg, Pennsylvania, to look and to watch," he said. "And the statement of Robert E. Lee, who's no longer in favor--did you ever notice it? He's no longer in favor. 'Never fight uphill, me boys, never fight uphill.' They were fighting uphill, he said, 'Wow, that was a big mistake,' he lost his great general. 'Never fight uphill, me boys,' but it was too late," Trump added.
"Gettysburg, what an unbelievable battle that was. The Battle of Gettysburg," the former president said Saturday. "What an unbelievable―I mean, it was so much and so interesting, and so vicious and horrible, and so beautiful in so many different ways."
