My read on it Sam suggests that Trump will not only get some Sanders' dissident votes but, just as good;a large percentage of Sanders voters simply won't cast a vote, at all.

This will be a turnout election, imo coupled with how the Independents and various unions roll.

I'm seeing a deja vu of the Reagan election.
