Hillary is going to be Obama's loudest, most passionate surrogate this fall; people expecting her to concede then disappear, or pull a Reagan 76-esque wink wink nod nod are...bitter! If it's true that she wants Obama to lose so she can (once again) run as the party's savior in 2012 she's going to have to make sure very few people think she hijacked Obama's campaign. That's why she won't take this to Denver. After the primaries she'll go back to NY and say "hey, this was soooo close, btw I won the popular vote. Anyway I'm going to be campaigning with and for Obama, and you should too!"
And if Obama loses she'll be able to say I told ya so. But interestingly, this is similar to the plan she had for THIS election: swoop in as the superstar rockstar historic savior of the party, take the presidency handily, and secure a place in the history books. Of course Obama took all that away from her. Is there anyone who could do that to her in 2012...?
