My new Bloomberg View column.

Robert Kagan, a neoconservative writer, has a theory about Donald Trump: He has risen to the top of the Republican field because the party has taught its members to value obstruction and hate President Barack Obama.
The more detail Kagan puts into his case, the less plausible it appears. So, for example, he decries “the persistent calls for nullification of Supreme Court decisions” as the kind of thing that led to Trump — who has said very little about Supreme Court decisions and nothing about nullification. If “the party’s wild obstructionism” was the portent, then why is the leading primary candidate the guy who keeps promising to make deals?
