How does the Republican Party of the future win over minority voters?

[Statilius the Epicurean]

There's no reason for Republicans to risk a huge chunk of their white support to go after Latinos who are concentrating themselves in the major cities of a handful of large-population states. If they can maintain 2016 numbers with whites the GOP will have an enduring structural advantage in Congress and in the EC, and who cares how many minorities you lose if they're gerrymandered out of the way?

If I were a Republican strategist I would basically advise what the Trump campaign did: moderate on social issues, go hard on crime and terrorism and use some populist economic rhetoric to try and get northern whites voting like southern ones.
