So in this week’s column over at TPMCafe, I took a closer look at the abrupt abandonment of Common Core K-12 education standards by Republicans, who probably played a bigger role in their development than did Democrats. Since last year a majority of the people viewed as likely 2016 GOP presidential candidates have managed to come out against Common Core, some predictably (Cruz and Paul), some cynically (Rubio), some more in rhetoric than reality (Walker and Huckabee), and some just blatantly flip-flopping overnight without bothering to offer much in the way of explanation (Jindal).

This “slow motion riot” has left Chris Christie and especially Jeb Bush in splendid isolation as defenders of yesterday’s preferred GOP approach to education reform. You can debate whether this development is death on a stick for the “Republican Establishment” candidates, or just one of a number of obstacles between them and the White House. But it’s a pretty big deal in any event.
