I suspect that, somewhere in the cancerous bowels of Clinton campaign HQ, there are some ugly internal polling numbers. The candidate, and her surrogates, are starting to sound scared - the kind of "scared" you hear from people who thought something was in the bag, only to have the rug pulled out from under them at the last minute.
You can see it everywhere you look. Hillary's cronies are melting down during interviews, Obama has abandoned his 'hands off' stance in regards to James Comey and seems upset by black voter turnout, and Hillary Clinton, the candidate herself, has gone into feverish fits of accusatory shrieking.
OK, fine, she shrieks a lot. But this is something new....
