Joe Biden Can't Beat Trump by himself

No hes an old man like trump, and might forget where he is. He might be able to beat up trump; but he might forget where he is and gets knocked out by trump. Thats why we got the other presidental candidate Kamala. In a 1v2, if they can't beat trump; the democratic party is honestly just putting up weaklings that can't properly win even a 1v2. We need presidents that can't lose an outnumbered fight and have the number advantage
