The Miami native who some, including us, thought could lead the Republican Party in finding a reasonable path on comprehensive immigration reform and help it broaden its appeal to minorities in America could not find the spine to do more than mildly criticize Trump after his blatantly racist attacks on four Democratic congresswomen.

Trump told the women that they should “go back” to the countries they came from instead of complaining about his policies — never mind that three of the women were born in America and the fourth has been a U.S. citizen longer than Trump’s own wife.

Rubio wouldn’t say if he thought Trump’s racist tweet was racist. He only conceded that, “The president shouldn’t have written that.”

Even after Trump whipped a crowd in Greensville, North Carolina, into a hateful froth against U.S. Rep. Ilhan Omar that erupted in chilling chants of “Send her back! Send her back!” — Rubio couldn’t muster the courage to truly object to the horrifying display of blatant racism. He called the chant “grotesque,” which it was, but he reserved most of his vitriol for “left wing politicians and many in the media.”
