Sorry delegates do matter. They are what matter more than anything else.
I disagree (and my reasoning is above).
Hypothetical Situation:
the primary goes to a brokered convention, and Mitt Romney carried all the swing states (ohio, florida, virginia, north carolina, pennsylvania) and Santorum carried only republican strongholds (Georgia, Texas, Oklahoma, etc) Santorum has more delegates, but neither one has a majority.
Who would have the strongest argument for being the party nominee? Serious question.
My answer here would be (obviously) that Romney would, despite having fewer delegates he would obviously be the stronger candidate- since Santorum is only competitive in states republicans would carry regardless. Once the delegates are freed to vote as they please, it becomes more about who has the strongest argument for winning in november, not whose delegate count was higher (but not high enough for a majority.)
Obviously this primary is more complicated than my hypothetical (and you could easily substitute a catastrophic late game "herman cain" or "newt gingrich" like breakdown in support for the leading candidate instead of the swing state example I posted), but you see what I mean here. Swaying a delegate to change their vote is going to be centered around logical and emotional appeals about who is the stronger candidate- not the primary delegate count.
