The entire accusations of “plagiarism” against Obama in his speaking are bogus.
There is a qualitative difference between a politico using someone else’s catch phrase, which is done all the time, and what Joe Biden did in 1988, when he lifted an entire speech and life story.
John F. Kennedy’s “Ask not what your country can do for you, ask what you can do for your country” phrase came from a speech from Warren G. Harding, for example.
This some seriously lame stuff.
