Meanwhile, in the USA
Meanwhile, the neverending story visits Kentucky and Oregon tonight and (spoiler alert) Obama will clinch a pledged delegate majority, but Hillary will win Kentucky and fight on.
Cherniak makes a good case for Hillary staying in the race until the end and I do think Obama's win at a contested DNC would generate a certain amount of excitement and create some momentum. However, the logistics of running a Presidential campaign are such that the Democrats simply can't afford to wait until late August to crown a nominee.
Puerto Rico holds the final primary on June 7th. I think a fair solution would be for the super delegates to make their choices public soon thereafter, so that Obama's win can finally become "official" and he can focus on setting up a national campaign and attacking John McCain. The DNC will, I'm sure, give Hillary a prominent role at the convention and find some way to recognize the strength of her campaign, but to delay the inevitable by nearly three months for...well, I can't think of any good reason...just wouldn't be fair to Obama, to Clinton, or to the Democratic Party.
UPDATE: Clinton takes Kentucky by an impressive 65%-30% margin.
...and Obama's looking good in Oregon - 63% to 37%, with 11% of the polls reporting.
