I think Monty is correct as to those who self-identify as Dems. The large bulk of those on the moderate wing may not love a nominee Sanders, but they'll pull the lever FOR him rather than aid Trump by voting third party in protest. Even Dem moderates do not view Trump as 'just another GOP type.' The issue will be among those of our "mugwumps," especially in the swing states, who are always the last to make up their minds and likely to react to the mood of the moment as the campaign finishes in late October.

Unlike Monty, I am not quite ready to write Bloomberg out of the story. Deep pockets and huge media buys may yet give him the tools -- but he has NOT instantly eclipsed the other moderates and, so far, it seems to be Sanders who is picking up the most steam from Bloomberg's foray.

And yes, Monty, I am one of those with a dash of personal respect for Sanders. I disagree with most of his policy initiatives and his political philosophy, but he has, pretty consistently, stated that he was and is a proponent of democratic socialism and put that to the fore in a country that is NOT traditionally receptive to same. Kudos for his honesty at least.
