What does Hillary need to do in order to appeal to more white males?

The same way Barack Obama did - run a smart campaign with a finely crafted, logical, inspiring message about economic issues.

There are some white men (i.e., those who support Bernie in the primary) who don't support her now but will probably support her in the general regardless of what she does.

There are some white men who won't support her even if she mails every white man a check for $100.  These are mostly the same people who didn't support Obama in 12.

Because of demographic trends, Hillary can do somewhat worse among white men, keep all other cohorts stable, and still win comfortably.  So she could potentially still win hemmorrhaging white men but with a strong democratic swing among women and latinos.  I wouldn't try it, but it might work.
