Frum, whose article "The Great Republican Revolt" is the cover story of the January/February issue of The Atlantic, argues that the Republican Party is now divided on class lines.
"The people who write the cheques and the people who run the party in Congress are one group of people," said Frum.
But on the other side of this class divide remains an overwhelmingly large group of voters who do not have a college education and who have struggled to do well in the American economy â?? this is the core Trump has tapped into.
