Donald Trump spent Monday morning labeling the turmoil in the global financial markets the “Kamala Crash,” giving Republicans hope that he might turn his focus to an economic message.

It didn’t last. By midday, the former president was already back to re-litigating his controversial appearance in Chicago last week, where he questioned Kamala Harris’ Black identity and suggested a major network journalist should be fired — “I didn’t know who she was, she was nasty,” he told a livestreamer.

Republicans on Monday reeled from Trump’s undisciplined approach to the opening stages of his new general election matchup with Harris — following a weekend that saw him praise Russian leader Vladimir Putin while smearing Harris as “low IQ,” and “dumb” and attacking a popular swing-state GOP governor whose turnout operation he may need in November.

“This is what you would call a public nervous breakdown,” said Matthew Bartlett, a GOP strategist and former Trump administration appointee. “This is a guy who cut through the Republican primary like a knife through butter. This is a guy who pummeled a semi-conscious president in a debate and literally out of a race. And now this is a guy who cannot come to grips with a competitive presidential race that would require discipline and effective messaging. And we’re seeing a candidate and a campaign absolutely melt down.”
