The only thing that really matters now is the final delegate count. If Romney gets the required 1144 (not very likely at this point) then what the others have makes no difference. If he gets slightly less than 1144 (more likely) then the party leaders can fanangle some of the unpleadged delegates and get him over the top. If he gets much less than 1144 (unlikely but quite possible), thats when people get to throw around politcal power and try to get concessions. However, I sincerely doubt ron paul will have much power, I think it would be more likely that Romney tries to get some ins with the very very conservative crowd by making nice with santorum (or to a lesser extent gingrich), maybe offering a place in the cabinet or something.
