I've pretty much just lurked throughout this whole Hatfield-McCoy feud that the Democratic nomination process has evolved into, but allow me to throw a couple of comments in;
-Having personally lived through enough election cycles, I've come to realize that the process is designed specifically as presently constituted for several good reasons. The election isn't merely a popularity contest; it's a ridiculously long, grueling affair purposely designed to winnow out those candidates who cannot problem solve, overcome objections, or properly assemble and then delegate to hand-picked staff to handle everything just the right way to "stay on the tracks" all while still retaining enough popular support to achieve their goals.
Just like the Presidency.
-While there is tremendous hand-wringing about all this at the moment, regardless of the eventual winner, this will all be forgotten by labor day after the dust of both conventions has settled and everyone focuses in on the general election.
Either democratic candidate will be severely battle-tested by the time one arises from the ashes. And no matter how you spin it, that is a good thing.
Keep your focus on the big picture.
