The outcome of the U.S. presidential primaries was supposed to be Hillary Clinton, the wife of an ex-president, versus Jeb Bush, the son and brother of other ex-presidents: both worthy but somewhat boring candidates, and both definitely members of the "establishment." Less than a week before the first primary, the Iowa caucuses, Bush is dead in the water and even Clinton is looking vulnerable.

In Bush's place as the Republican front-runner is Donald Trump, billionaire property developer, TV reality star and demagogue, who told a campaign rally last weekend, "I could stand in the middle of 5th Avenue and shoot somebody and I wouldn't lose voters." His arrogance is not misplaced: To the despair of the Republican Party's hierarchy, he probably has the party's presidential nomination locked up.

Three months ago, Democrats thought this would virtually guarantee Clinton's election, as a majority of Americans would refuse to vote for such a crude clown. That was probably correct, but it's irrelevant if Clinton doesn't get the Democratic nomination. Ominously, her "socialist" rival, Bernie Sanders, is neck and neck with her in Iowa and clearly ahead in the next primary, in New Hampshire.
