“He spent four years preparing for a run against Joe Biden."...

Adding to the sense that Mr. Trump is flailing about, this week he has been testing out a new mocking nickname for his opponent, referring to Ms. Harris as “Kamabla.” It is a departure from the previous epithet he had chosen (“Laffin’ Kamala”), and nobody seems quite sure how to decipher it.
