The final words

I read this American Prospect post on the damage Clinton is doing yeterday, but didn't post it because, I figure, you know what I think, and you know what you think. But the final sentences stayed with me, coming back much later in the day. So...

By threatening to keep the campaign rolling into summer, though, Clinton isn't just running up against the Obama forces; she's taking on Newton's Third Law of Motion: For every action, there is an equal and opposite reaction. There are few if any Clinton-uber-alles supporters among the 200 or so still undeclared superdelegates. Nothing would push them more firmly into Obama's camp than a Clinton attempt to prolong the agony of the Democrats' contest (which, if it were a Shakespearean play, would now be into Act VIII). Indeed, if Clinton presses on beyond next week, when Obama will surely win the number of delegates required for nomination, it won't be surprising if some of the superdelegates who back Clinton shift to Obama's column. By keeping her campaign going, Hillary Clinton can damage Barack Obama and herself. The only presidential candidate she can't damage is John McCain.
