The undisputed leader of the clown wing is Donald Trump. In a self-promotional joke gone awry, the Donald surged to the front of the pack of presidential wannabes on the strength (?) of overtly racist attacks on Latinos, dismissive attacks on other candidates, and unprecedented, not to mention unpresidential, self-aggrandizement. If you were lucky enough to have missed his recent antics, let me welcome you back from your trip to Pluto and update you: In a meandering candidacy announcement, Trump said, in essence, "some of my best friends are Mexican," while accusing the Mexican government of exporting its "problems," namely drug dealers and their worst sorts of rapists — mother-rapists, father-rapists, you name it. Trump's business ventures took an immediate hit. NBC, Macy's, Serta and Univision dropped their dealings with him faster than a hot tamale; not satisfied with offending an important voting bloc, he repeated his charge in several other interviews, adding that "there's not a racist bone in my body." Others were not so sure of his claim.
