Sen. Cory Booker, D-N.J., is shocked — shocked! — that former Vice President Joe Biden would boast publicly about his history of working civilly in the U.S. Senate with segregationist Dixiecrats. Booker is so shocked, in fact, that he is registering his displeasure with any newsroom that will listen, making headlines along the way with juicy sound bites and quotable quotes.

Of course, Booker’s public remarks this week have also done wonders for his campaign’s previously nonexistent media exposure.
