Amy, sadly (for her) she's all done, I heard she went home after Nevada's disastrous showing.
The old saying is that you can't beat somebody with nobody. So far the anti-Sanders forces just have several nobodies. Maybe the Hildabeast will come to their rescue. Or perhaps one of the failures from yesteryear--Al Gore or John Kerry. Both of them are veterans, you know. John Kerry was even sent to Cambodia by President-Elect Nixon in December 1968.
Makes some sense for the Dems to rally around Sanders now and avoid a brutal primary season. The media then will get onboard and give him top cover like they did for Obama.
