You are correct,...probably best not to mention Brooklyn, the last time he lived in Brooklyn was when he was a teenager back in the '50s. He moved to Vermont back in '68 almost a half century ago. Vermont is a rural state, with a few small to midsize metropolitan areas.

Since that is the analogy you're shooting for, I'm sure it does,...to you, and many here-bouts. If it turns out that way, mores the pity for the nation. But regardless of what happens to Senator Sanders, it won't make Hillary an acceptable, progressive candidate. Anything less than that is a loss for everyone, it doesn't matter that she's less corporatist or less conservative than candidates on the other side, it is still a loss for all.
If Sanders had never run as a Democratic candidate, I still would not have been a Clinton supporter this time around, and I won't become one if Sanders loses in the primaries. I'm very unlikely to support a GOP candidate, but I can't conceive of a situation where I would support Hillary. Nor, however, will I sit at home.
