Trump moved closer to the GOP nomination by winning seven states on Super Tuesday. His campaign has taken a hard stance on trade and immigration, proposing tariffs, militarization around China, cracking down on intellectual property violations and limiting visas.
Trump's rhetoric is bad for stocks that are international, like Starbucks and General Electric, Cramer said on Squawk on the Street," because companies that are representative of the U.S. could feel a backlash against Trump's policies.
"If I were one of these international companies, I would be saying, 'I don't need this headache. I've got the strong dollar, now I've got the president saying these things,'" Cramer said.
Chinese consumers might be turned off from items like Kimberly Clark diapers or products from GE and Honeywell, he said. Cisco might have to defend its strong partnerships in France. Kimberly Clark, General Electric and Cisco declined to comment, while other companies did not immediately respond to CNBC's request for comment.
Starbucks' brand is a leading symbol of U.S. business abroad, said Cramer— and could get swept up in Trump's agenda.
"If I were ... Howard Schultz, I would be saying, 'I should have run for president, for heaven's sake,'" Cramer said. "If I were [Disney CEO] Bob Iger, I would not be contributing to Trump's campaign — I've got Shanghai Disney opening up."
Disclosure: Cramer's charitable trust owns shares of Starbucks.
