Carl Bernstein on CNN just said that he's talked to Clinton strategists and their only way to win the nomination is to go so negative on Obama that they will sway the superdelegates.
And what's sad is, this should not be news! Of course it's their only way to overtake Obama. Can someone please send the MSM a calculator? Or at least point them to the one that comes with every version of Microsoft Windows?
"Momentum" doesn't magically equal pledged delegates.
Bernstein has been writing a biography on Hillary for the longest time, so he probably has excellent contacts.
