Over what issue(s) would you feel betrayed?

One of my few remaining reservations about Obama has less to do with him than with the expectations of his most passionate supporters. We expect "change" if he is elected -- though what is meant by that is open to wide interpretation. Perhaps it means a change in the tone of the "discourse" (badly needed and most welcome). But many identify that "change" with a specific policy. Suppose Obama is elected and, given the political realities which constrain the White House, he backs off or goes against you on a specific issue or cluster of issues. Which ones would you yield without feeling betrayed, and over which ones would you be bitter that he had broken the promise? I suspect that Obama would do a lot of good, even if only in terms of the discourse, but I also expect him to be bogged down and derailed by opposing forces on most attempts to "change" the direction of the country. Change comes slowly. But expectations for an Obama presidency are high -- and sometimes ill defined. What would be your "gold standard" for deciding whether he had come through for you?
