Marginalia

There are people who will support Trump no matter what, the 27%. The question is, to what degree do we need to understand and reach out to those people?  There is a decent argument that the answer is: not at all.

The persuadable Trump voter exists.  The persuadable Trump supporter does not.  There are those who - foolishly - felt that Trump could be trusted because he simply wasn't Hillary.  Decades of smearing Clinton paid off, combining with Comey's unprecedented interference to toss the presidency to the Shitgibbon by narrow margins.

Many of those voters will abandon Trump - are abandoning Trump - as the cascade of scandal and dysfunction continues.  If the media can uncover true links between Trump and Russia, that will erode his support even more. Town halls are erupting in unrest.  The heat is building.

As for the hard core Trump supporters, fuck'em.  They will never be convinced; evidence will simply convince them of the opposite.  Plus, keep in mind this:

You mobilize a fraction of that lower right cohort and you start to flip not only the White House in 2020, but the House (and possibly the Senate) in 2018.
