"I'd like to hear and understand what voters saw or heard in his message"

You would have to sink to a 5th Grade mentality to understand them. 

The mistake Democrats made was to "go high when they (went) low."  Nice kumbaya thinking.  But not effective.  
Trumps' followers understand going low and we should have a tookset they would have understood and spelled it out for them.  
In the next 4 years... Democrats need to go "low" to have any effect or gain any power.  This is all little white men and their women who want to make them feel bigger understand.
