How will good Hillary Clinton soldiers attack Donna Brazile's character?
I don't know that they will. The Dems with whom I've had conversations about it acknowledge the verity of Donna's remarks. That they do is a key difference I observe between key/influential Dems and the Trump genre of Republicans. Neither is keen to be criticized, but unlike Trump and his Trumpkins, Dems who matter don't launch into staccatos of
vitriolic character assassination targeted at the messenger of disconcerting truths, especially when the messenger's is by and large predisposed to be a force of positive change for Democrats.
After all, constructive criticism delivered by an ally is among the most useful forms of input one will ever receive. One'd be foolish to, by volleys of insults, transform a friend into an enemy. While Democratic "movers and shakers" exhibit their share of foolishness, they, unlike Trump, are not so foolish as to "implode" or bifurcate their party by pursuing a "scorched earth" approach to countering remarks they know are true. They just aren't that emotional or that irrational.
