Here’s another example of our president abandoning any pretense that he’s the leader of a white nationalist movement.

President Trump on Sunday weighed in on the friction between a group of four freshman Democratic congresswomen and Speaker Nancy Pelosi: He suggested that the congresswomen — none of whom are white — should “go back and help fix” the countries they came from. His message was immediately seized upon by Democrats, who called it a racist trope.

“So interesting to see ‘Progressive’ Democrat Congresswomen, who originally came from countries whose governments are a complete and total catastrophe, the worst, most corrupt and inept anywhere in the world (if they even have a functioning government at all), now loudly and viciously telling the people of the United States, the greatest and most powerful Nation on earth, how our government is to be run,” Mr. Trump wrote on Twitter.

The “Democrat Congresswomen” Trump was referring to are Reps. Alexandria Ocasio-Cortez (NY-14), Ilhan Omar (MN-05), Ayanna Pressley (MA-07) and Rashida Tlaib (MI-13). Now, it’s true that Rep. Omar was born in Mogadishu, Somalia on October 4, 1982, and it seems like Trump’s comments were directed at her. Except he didn’t single her out. He said all four of them should return to their countries of origin.

That won’t be easy for the others to do.  Rep. Pressley was born in Cincinnati, Ohio on February 3, 1974. Rep. Tlaib was born in Detroit, Michigan on July 24, 1976. Rep. Ocasio-Cortez was born in The Bronx, New York City on October 13, 1989.

If we want to go a little deeper, Rep. Tlaib’s parents are Palestinian. Ocasio-Cortez’s mother was born in Puerto Rico but that was and still is part of the United States of America. Pressley’s parents were born in the continental United States. Her family has presumably been here for generations, possibly even many centuries, and certainly longer Trump’s family.

Of course, these distinctions don’t really matter. What the president said was despicable irrespective of the accuracy of his assumptions. I mention them just to provide the full context. He’s treating elected representatives as if they are not even American citizens. He’s saying that their perspectives are foreign and invalid because of their ethnicity.  He’s arguing that they should go represent Palestine, Puerto Rico, and the African countries from which their families originate because their opinions and votes are not welcomed here.

Perhaps part of his intention here is to cause some problems for Speaker Pelosi who has been having a bit of a dispute with the four freshmen. But that’s not really the key political play here. Trump is playing hard to his white nationalist base, fully knowing that every decent person in the country is going to recoil and condemn his remarks. He still sees it as a winning move.

When I say that Trump is abandoning the center, this is a prime example. The Democrats should be able to just plant themselves on the ground that Trump is ceding and take the White House from him with ease. But, they can still blow it if they careen off so far to the left that the center becomes a battleground again.

I’ll have more to say about that when I write up my impressions of the Netroots Nation conference that just concluded in Philadelphia.
