text: I don't understand the attachment of white evangelicals to Trump in any shared values.   That leads me to believe they are exactly the voters that 'identity politics' persuaders love to see.  Ex.   White, above average income, authoritarian friendly,(should be servants to god, but the professionals can transfer that to human leaders easily). 
  
  Just find out what that group wants to hear and tell them.   Simple, and it doesn't have to be true.  Be sure not to get tied down by facts if you want the vote.
  
   That's identity politics and The Party uses it on a public mostly disinterested in the details of governing.  If the voter sees something 'like us' in a candidate, they go that way.   They have no time or interest in complexity of policy, they have other things to do.
