What would President Obama's/McCain's policy be WRT Cuba?

I haven’t heard either of them mention Cuba so far this campaign (though I may have missed something). Is it possible that Obama, at least, would make some moves towards dropping the embargo and normalizing relations?

He might agree to talk to them without preconditions, and then we would lose!

And McCain would bomb them, Biden would demand they recuse themself from OPEC, and Palin would first have to figure out where it is before she asked McCain what her position is.

It seems that a likely strategy is to do nothing, wait until one or both Castros are dead and see what happens next. Unfortunately that doesn’t make for good sound bites.

Obama also specifically said during one of the primary debates that he would meet with Raul Castro without preconditions.
