Those are my principles, and if you don't like them ... well, I have others. — Groucho Marx
The odds have lengthened against a Donald Trump presidency after his Wisconsin defeat, and they were probably already 10-to-one against. If he wins the Republican nomination, which is still very likely, he will almost certainly face Hillary Clinton in the November election, and lose badly.
Or at least that is the orthodox calculation, for Trump is far behind Clinton with key voter groups like women, Latinos, African-Americans and young people who bother to vote. But she is an uninspiring campaigner, she is the ultimate Washington insider in a season where insiders are out, and there are a few skeletons that might come rattling out of her closet during the campaign. A big terrorist attack could also change the odds.
