Trump didn't name names...but they eventually self-identified.
If the shoe fits....wear it.
What he said could apply to every Democrat.
Democrats live in districts that are literally 3rd world shitholes.
Trump has been listening for months to Democrats complaining about how much America sucks.
So his answer to that was, "Before you complain about America....why don't you go back to where you live and fix it first".
Democrats love illegals and ignore the homeless living in the streets that surrounds their mansions back home.
What he said wasn't racist.
The 4 members of the Death Squad have been bitching and whining about America for months and doing nothing about it....other than making it worse.
He simply pointed out their hypocrisy.
Trump's the most recent racist incarnation of one of three factions that was dominant in US politics prior to the (first) US Civil War:
Trump's Racist Tweets Fan Hatred, Defining the Coming Election
" There was a pro-slavery faction in Dixie.
"There was a white man’s country faction that said that black people should not be part of the United States of America and the only people who should be part of the United States of America are those defined as white..."
" Now, the historians mostly focus on the third faction, the abolitionist faction— John Brown, Frederick Douglass of Baltimore, William Garrison of New England, etc.
"But that’s a misreading of history and I think what’s happening now is that Mr. Trump is bringing to the surface this white man’s country faction, which encompasses— I’m afraid to say— a goodly number of his 63 million-strong base that voted for him in 2016, and are probably going to vote for him again in November 2020."
