Thanks for the link.
That thread about the Politico thing started at 9:23 pm PST, some time after I did my search. It reminds me of some details in the CBS radio thing: he was supposed to drop out if he didn't get at least second place, and he was supposed to endorse McCain.
It also reminds me of how the CBS radio thing attributed this idea to "sources" of some sort (I forget what). Don't you just love sources?
