Not since George Wallace’s campaign in 1968 has a presidential candidate — and certainly not an incumbent president — put racial polarization at the center of his call to voters. Though Trump’s comments generated outrage and even a resolution of condemnation in the House, the president and his campaign believe the strategy carries far more benefits than risks.

“Regardless of whether his tweets are racist or not — I’m not saying they are or not — he is getting the media to make these extremely liberal, socialist, foolish congresswomen the face of the Democratic Party,” said Terry Sullivan, a frequent Trump critic who managed Sen. Marco Rubio’s 2016 Republican presidential campaign. “What he’s doing here is sad, but it’s smart politics.”

Still, there are clear perils to his approach.

Educated suburban voters, especially college-educated women, and minorities in key states like Pennsylvania, Michigan and Wisconsin were already threatening to revolt against the Republican president. Trump believes his inflammatory rhetoric will strengthen his support among the white working class and attract a new group of disaffected voters who fear cultural changes across America.
