There is a lot of debate on this site. Some good. Most of it is minutiae.

When Hillary waited until they were together until she decided to walk over a greet Ted, does anyone think  that was an accident? She knew that he would shake her hand, and with Obama standing there it makes a great photo op, to diffuse what has been the biggest endorsement in the primary to date.

At the very least.  

But I would like to ask a different question to you Hillary supporters..

"What would you have liked for Barack to do while his most prominent endorser chats with his main political rival?"

For once stop with the rhetoric and answer the question.

Should he have just stood there looking awkward? That photo op would have been a nice win for Hillary.
Should he have extended  his hand when obviously Hillary didn't come over to shake it?  Perhaps, but why? Does anyone here try to shake hands with people who are conversing with someone else?
Perhaps he have felt insulted that she basically walked over, talked to Ted and ignored him? Maybe he thought, SHE snubbed him?

No he did the civil thing. Just try to look away while Ted tries to mend a friendship.

And by the way, how did he 'snub' her, if she wasn't looking to shake his any anyway?

The next thing you all will be saying is that it was a TOTAL accident that she decided to wait until they were standing right next to each before she came over.

If she really was being genuine in trying to display a PDA for her old friend, she would have waited until Barack wasn't around and Ted wouldn't have felt embarrassed.
Or better yet, meet with him privately to tell him , "no hard feelings."
