There was what President Obama likes to call a teachable moment last week, when the International Olympic Committee rejected Chicago’s bid to be host of the 2016 Summer Games.

“Cheers erupted” at the headquarters of the conservative Weekly Standard, according to a blog post by a member of the magazine’s staff, with the headline “Obama loses! Obama loses!” Rush Limbaugh declared himself “gleeful.” “World Rejects Obama,” gloated the Drudge Report. And so on.

So what did we learn from this moment? For one thing, we learned that the modern conservative movement, which dominates the modern Republican Party, has the emotional maturity of a bratty 13-year-old.
