Completely agree. Although he has lots and lots of company, Biden really is one of the worst on many issues of interest, for example privacy[1]. And it's ironic that he often presents copyright as a moral issue, equating copyright violations with theft, when he was caught copying 5 pages out of a law review article in 15 page paper he submitted in law school[2] and then there is the plagiarism in some of his speeches[3].
Yes, they are all the same. Except that some are much more the same than others.
There would have been few you could pick that would have made me less happy than Biden. Unfortunately two on that short list are Sarah Palin and Paul Ryan.
