March 20

* The Obama administration announced new sanctions on Russia, a group of 20 high-ranking Russian officials, and a Russian bank.

* The Russian government turned right around and announced their own sanctions on a group of American government officials, apparently chosen by someone in the embassy making a list of people they saw on cable TV. With Mary Landrieu now barred from entering Russia, global tensions have reached a new height.

* Chris Cillizza pays tribute to C-SPAN, which turns 35 this week.

* In The Atlantic, Hannah Rosin examines how we’re overprotecting our kids, and what might become of them as a result.

* Jonathan Chait looks at the different ways white and black basketball players are talked about by announcers, noting that somehow none of the black guys are referred to as scrappy, overachieving kids with tons of hustle, even if that is indeed what they are.

*President Obama pushes back on Bill O’Reilly’s insistence that Abraham Lincoln wouldn’t have gone on “Between Two Ferns.” “If you read back on Lincoln,” said the president, “he loved telling the occasional bawdy joke and being out among regular folks.”

*Scott Lemieux considers whether Justice Ruth Bader Ginsburg should retire before the end of Obama’s term, and says the real answer is term limits for the Supreme Court.

* Carlotta Gall reports in the New York Times Magazine that Pakistan’s intelligence service not only knew where Osama Bin Laden was for years, they actively worked with him.

* When you’re such a sexist jerk that Tucker Carlson feels the need to apologize for your behavior, you’ve really accomplished something.

* Twitter has a new tool that lets you find your first tweet, or anyone’s for that matter. Mine was a link to an article i wrote (boring, I know). Greg’s read “My kingdom for a cup of coffee,” a sentiment I heartily endorse.

* And finally, here’s a full-size car you can actually drive, made of Legos. The human spirit is truly inspiring.
