"Standing in a room in Philadelphia, with the words 'Writing the Constitution' over his right shoulder, Obama gave a speech that almost wholly ignored Biden, whom he’d ostensibly come to praise."
The above is false. I saw him give the speech and he spent a lot of time talking about Biden - the many tasks Biden did to help the country when he was Vice President and spoke about Biden's caring for others.
I had forgotten about Biden having a vocal stutter problem when he was young; in a time past, I read about that. At some point, when in public office, if he came across a child who stuttered, he would speak to him/her and give his phone number so he could talk to the child privately and try to help that child; telling the child what he did to get rid of the stutter. I read what he did to get rid of it.
Biden is a Democrat but also a person just like us. All people have problems because they are humans. Take away the politics, and we are equal.
