I'll have more comments on my recent trip to Europe, but first....
Now that the dust has settled from Pennsylvania, has anything changed? Although much of the press--including the estimable TPM--spoke of a "decisive" Clinton victory, it was nothing of the sort. Keeping her campaign alive was not a decisive victory; it was merely the avoidance--delay, really--of the final failure.
As of today, John Edwards is almost as likely to get the Democratic nomination as Hillary Clinton. Hell, Joe Biden is almost as likely.
(English usage note: In TPM, Josh Marshall wrote, "I'd say the real story is that this leaves us basically where we were. It was a decisive win for Hillary but that was the expectation." I emailed him to note the contradiction and he took the time to write back, defending his usage because of the numbers. Well, no. That's really journalistic sloppiness.)
