Trump’s new nickname for former Vice President Joe Biden should go from “Sleepy Joe” to old “Mumble-Mouth.”

Biden made another serious gaffe when he told a crowd in Iowa that “poor kids are just as bright and talented as white kids.” For the Democrats, who keep haranguing President Trump with the diatribe of “word’s matter,” maybe they should rethink hanging so much of their hopes on a frontrunner that seems to really enjoy the taste of his own foot.

Biden, who famously directed supporters to a wrong number during last month’s debate — and just misidentified the sites of recent mass shootings — quickly corrected himself after some applause from the crowd at the Asian & Latino Coalition PAC, and finished, “wealthy kids, black kids, Asian kids.”

Biden, who in 2006 drew criticism with a comment about Indian-Americans moving to Delaware, the state that Biden represented when he served in the U.S. Senate, also told a crowd at the Iowa State Fair that “we choose science over fiction. We choose truth over facts.”

Biden, like all of the Democratic candidates, has put blame on President Trump’s rhetoric for playing a role in the recent mass shootings in El Paso, Texas, and Dayton, Ohio. He said Trump is “using the language of white nationalists.”

The former Veep also told CNN on Monday that Trump talks about Muslims and people of color in “almost subhuman terms.”

Sleepy Joe obviously could not take his foot out of his mouth long enough to praise Trump earlier this week, when the President called on the nation to condemn white nationalism.

But instead he chose to attack Trump because he refused to apologize for his incendiary rhetoric on race, and yet, Biden — who has been questioned about his stance on busing by members of his own party –continues to make some racially charged comments of his own.
